powerful gaming desktop advice

It could be Aby Som3a, you could probably just use a 600w PSU for a Single HD4870X2 and then buy that VGA PSU to run a second HD4870X2, and call it a day. You'd have to look up some reviews though.

Do people care about price-performance and diminishing returns, or do they completely ignore common sense? 😕

Why the hell would you XF two 4870x2's?

 

[Roguestar]

Because you need to pay more for your setup if your enjoyment comes from telling people what hardware you have.

do I really need a bigger psu? already ordered the 1000 watt... damn it. it is covered by newegg standard return so I should be fine.



**if you don't like it get out of my thread. I asked for advice not trolling.

 

[omghaxcode]

what are some good 1200 watt psus?

I have my heart set on crossfire because I like to max graphics and enjoy games like a movie. I understand that it is a huge price to pay for what some might think a trivial benefit but I don't mind paying. as for the 1000 watt supply, isn't that a bit low for these cards? I thought 1000 would be like the bare minimum. also I know that CPU is great but is it up to the level of that crossfire system? I don't want to be limited by CPU. thanks for your help

From Guru3d:

CPU scaling in games with dual & quad core processors

Cliffs: At resolutions 16x12 and up - it's all GPU. Dual/quad or AMD/Intel - no worries.


Tech Report: HD 4870 Power Consumption @ Load

HD4870x2 (X2) 'Quad CrossFire' = 752w
HD4870 (x3) 'Tri - CrossFire' = 626w
HD4870x2 single card or HD4870 (x2) CrossFire = 448w


That said .... mobos with 2 x PCIe Gen2 "x16x16"

MSI K9A2 Platinum AM2+/AM2 AMD 790FX: $160

or

Foxconn A79A-S AM2+/AM2 AMD 790FX (sb750): $240

with a

AMD Phenom 9850 BLACK EDITION 2.5GHz: $194

and a

SAPPHIRE 100251SR Radeon HD 4870 X2 2GB 512-bit (256-bit x 2) GDDR5: $570


Going from 28-inch to 30-inch LCD basically doubles the price of the monitor. Is that worth it for you?

Here's the recommended list from ATI for crossfired HD4870 X2's. http://game.amd.com/us-en/cros...ex_components.aspx?p=3

True Power Quattro 1000W (TPQ-1000) can run two, which is 'just' $199. That silverstone isn't on the list but I bet it will work.

 

[Roguestar]

Heybooboo keeps recommending Phenom CPUs but there is little to no point in supporting AMD if they're simply not as good as Intel CPUs in the same price range.

 

[omghaxcode]

thanks everyone for your help. I've ordered my parts. TY

 

[Roguestar]

Good luck with your build, let us know how it goes and any issues you have :thumbsup:.

I saw 2 x 4870x2 used over 750w off the wall, and that wasnt gaming, just benchmarking....with HDD spinning up, CPU @ load, I wouldnt risk $1K on anything less than 1KW

So my modified build is fine?
