Is a 7900GT faster than a 7800GTX?

As above, please. Any reason (aside from a big price diff) to get a 7800GTX over a 7900GT?

Also, are there any real improvement to the core of the 79xx series over the 78xx series? Is the 7900 a better card?

Thanks.

I think it is +-. Sometimes one is faster sometimes the other. Overall at stock they should be more or less the same. But once oced and volt modded, I don't know whether the same can be done to a 7800GTX.

Both cards are almost identical with only clock speeds differentiating stock performance. However, the 7900GT is built on a more efficient process, so there is a lot more overclocking potential. 7900GT's are knocked for generally having poorer cooling solutions, but everyone I know has added an aftermarket cooler anyway. Also the 7900GT is very easy to voltmod to 7900GTX voltages.

Thanks guys, I appreciate the info.

CHERUB: Thanks very much, that's the kind of detailed info I was looking for.

So...if I got a 7900GT, by the time I purchased an aftermarket heatsink, and there's not guarantee on OCing...I might as well get the 7900GTX, huh?

No, there's no real point to buying a 7900GTX if you're going to overclock, remember eVGA will cover voltmods as long as it isn't obviously scortched when you send it back as such you might as well push the boat out and start having some fun with it.

Well the 512mb 7800GTX is basically a 7900GTX on a 110nm process...

Are you insane, volt mods are not covered by anyone. Please dont give advice on something you obviously know little about (warranty). If you volt mod you card and send it back to evga, you will get nothing back. The only type of hardware modification evga allows is third party cooling.

eVGA covers overclocks don't they? They also cover 3rd party cooling. Bwahahahahaha.I love eVGA

Is evga the only one that does this? I thought that if you removed the stock hs, the warrenty was voided.

Ah! Now we start with all the stuff that hurts my head. "The 7800GTX VOXO OC 512 is faster than the 7900GT..but not as fast as the 7800GTX OOOXOOOO OC, which is only available on Sundays."

/bangs head on keyboard

Anyway, I'd definitely be getting a "major brand card" such as EVGA. I have their 256MB 7800GTX (no overclock, doesn't run on Plutonium, etc) and it's been solid since day one.

I shy away from voltmods and the like b/c the possibility of nuking the card is a 50/50% shot. And I'd hate to flush $250+ down the toilet.

Now, I'll flash the bios and mess with OC software...just keep that conductive pen away from me....

-----------------

I am sure my 7800GTX oc' performs better than my 7900GTX2.....This is very s strange and cannot explain it!

Yes the GTX2 has better numbers and marks but performance is a Little better with the 256mb 7800GTX oc-WC.

I have 2 7900GT's. Vmodded the core on both (it's pretty safe, memory vmod is whats killing them all). Running rock solid @ 700/1620.
I have no complaints. Got 2 7900GTX's for a lot less money. (sure no 512mb of VRAM though)
