Hi ive currently got a 7800gtx but not an sli board and only a 500w psu.. and ive gotten some cash for my birthday and wondering what would be the better upgrade after i sell my 7800gtx.. a 7900gtx or a x1900xt or 7950gx2?
x1900xt / 7900gtx / 7950gx2

X1900 XT... IMO.
Cheaper, and seems to be a bit better at higher resolution/higher AA + AF settings.

If your 500W PSU is a quality one (not generic like those with your $50 computer case) then you are fine for either card. Make sure it has at least 28a on the 12v rail. The recommended is 30a on the 12v rail but so long as you don't have a ton of peripherals hooked up your PSU will be fine. Again, assuming it's a quality unit and not a pos.
Right now there is a very good deal on the X1900XT ($370 after rebate), look in the Hot Deals forum. There's also a very nice deal on the 7900GT ($240 after rebate). The 7900GT would be an improvement ONLY if you plan to do the volt mod and overclock. If not the X1900XT would be the better choice.

Ive got an antec psu but im in aus so i cant really buy stuff from us.
A x1900xt is about $600 - 650 around here , a 7900gtx is about $700 - 750 and a x1900xtx is about 730 - 800..

I'd check the benchmarks on the 7950GX2 before deciding. Those are insane prices for hardware down under. From various sites, it seems that at lower resolutions, the 7950GX2 provides no benefit over a X1900XT, it's only when you get to 1600x1200 and higher than the 7950GX2 starts to show it's stuff. Dunno if it's worth the price premium over the 7900GTX or X1900XT.
well its only $200 more and it is basicly a dud sli system it has 1gb on board ram so it would prolly last alot longer than a x1900xt for $200 more...
Not necessarily, it doesn't look like drivers at the moment fully support the card (not for long I suppose). If you are spending that much money, save it for when the dx10 cards come out next year? I don't think there are any games at the moment that a 7800GTX can't fully run at 19 inch resolutions.
hmm my 19 inch can do 1920x1440 and the 7800gtx really dies in the newer games at that kinda reso.. im just wondering will the 7950 actualy work in a non sli board? it said it does but has any1 done it? Also would my 3700+ @ 2.6ghz be a bottleneck?
No, the 7950 has to be installed in a SLI board because it is serious two overclocked 512MB 7900GTs sold in a pair, and therefore it has all the disadvantage of a SLI system.
??? no. Then again, I don't know what that price is in aus. as compared to US.
If you're wanting just faster frames, get the 7900GTX, or--if you can afford it--a 7950GX2.
If you're wanting faster frames and a better graphcis, get the X1900XT. The AF is better, HDR + AA support.
Overall, the 7950GX2 is a pretty neat way of making a dual GPU card in one PCI-Ex16 lane. Its 1 GBof ram is there for the whole system to use which is kind of nice. Also, it gives as many pixel shaders as the X1900XT(X) while also giving more vertex shaders. It does perform better, but looks the exact same as your 7800 does.
The X1900XT is a great buy if you ask me. Not only did I see performance gains going form a 7800GT SLI to a X1900XTX, but the enhancements that it did graphically to my games is awesome. The games I play look better as well as play better too. Plus, its memory is much more effecient than Nvidias due to its ring-bus system. 512 MB of ATI memory is (right now) better than 512 MB of Nvidia memory.
Thing is, right now isn't the best time to start upgrading computer components unless you want to have the Kings of an almost dead era. Conroe is around the corner, G80's and R600's are getting closer and closer, and DX9 Games are not looking nearly as cool as the DX10 ones coming up. The 7950GX2 is a unique design, and when I first heard of its existence I thought, "Oh, maybe they'll do something different to the 7 series GPU" Fact is, its still very, very much the same as your 7800 only smaller and coupled with another one without the SLI link. That's what has been turning me off about Nvidia recently. The fact that the GPU's aren't changing at all, just shrinking and multiplying.
ATI is on top right now if you ask me, just like Nvidia was at the reign of the 78 series. Next thing you know, Nvidia will be on top again, then ATI, then Nvidia, then ATI, then Nvidia, etc. you get the idea.
Buy what you want, just giving you my $.02
Well i wanna get the 7950 coz its almost the same as an sli solution but i dont have an sli board , and dx 10 is awhile off yet.. and the first round of dx10 cards prolly wont be able to handle all the decent dx10 games when they r out any way..
Who knows? No one can really assume much since DX10 isn't going to be like anyother DX version existent. The echoes of both G80 and R600 look very promising, and with the effeciency that DX10 is supposed to have, we really don't know if the first gen vc launches are going to be the same as the past ones.
Another thing, if you're really wanting to figure out which card to get, ATI is going to come out with a R580+ to compete with--I guess--the 7950GX2. It will have GDDR4 memory is the rumor.
All I'm saying is if you wait, you might see competition bring the best prices to you, and then you'll also see if you want to invest more in DX9 or wait a little more for DX10.

yeah but ati isnt know for its speed to bring out new products and the 7950 is a decent card thats gonna last a while since i cant sli without a new board. Another problem with dx10 id need a new psu.

From about 10 reviews that i read so far.. the 7950GX2 whips ALL competition. (i.e X1900XTX/XT,7900GTX) But consumes less power and less noise to boot compared to its direcy competitor, the X1900XTX. (Although its about $100 cheaper) while also taking up the same space!!
The 7950GX2 is about 50% faster than an X1900XT and it gets worse as in OpenGL games.

Yeah thanks for the advice but i just got abit of cash and looking for an upgrade now , to sli my 7800's id need new motherboard , psu etc , to get a dx10 card id need a new psu any way so this seems the best thing for now.
If you want to compare 7900GX 2 on a non sli board then compare it with RAdeon 1900XTX or XTX OC, XTX is better than XT.
Will the card even work in non sli board?

yeah it will ive looked around and it even says on the anandtech review works in non sli boards.. im just abit worried about my antec 480w psu not being enough
7950gx2
pro: fastest on planet,HDCP built-in
con: expensive
7900gt
pro: cheap, fast if overclocked
con: slow if you do not overclock
1900xt
pro: fast
con: loud, runs hot..

From the reviews I read on the web, another con of the card is that it dumps a lot of heat inside the system, which is why I probably won't consider it. I have the XTX now (borrowed) and although it runs hot it doesnt affect my ambient at all which is really helpful
This is definitely NOT true...the Techreport review of the 7950GX2 says it is still only a 512mb frame buffer...You do not get 1gb of video memory. It has the same limitation as if you had 2 7900GTXs in SLI. THey market it as a 1gb card but you certainly do not get a 1gb frame buffer, its only 512mb.
