A little advice.....7900 GTs ot 7900 GTX

[MaxRott]

So I am getting ready to build a new gaming rig... obviously SLI has been in my mind. I know some people hold the belief that SLI isn't all it's cracked up to be. I think I read somewhere that you can gain a potential 30% performance increase.

My question is this... should I toss in 2 XFX 7900 GTs 256MB (UDD 560/1650) or save a little money and put 1 XFX 7900GTX Extreme 512MB 690/1750 ? Would the SLI configuration have a much bigger performance increase over the single GTX.

These are the other components I am planning to put in the rig....

Case - Antec SuperLanBoy
PSU - OCZ 600W Powerstream
RAM - 2X1GB sticks OCZ DDR400 Platinum LL
Mobo - Asus A8N32-SLI Deluxe
CPU - AMD Athlon 64 X2 4400+
HD - WD Raptor 74GB 10k RPM
HD2 - WD Cavier 250 GB SATA II

Any thoughts / suggestions are appreciated.

Thanks
- Max

Go with a single 7900GTX, get the non-oc version as well (not worth the money for something that's free and widely available).

It's faster, quieter and runs cooler than 7900GTs.

Thanks for the input. That is what I will go with, I also have a TT Tide Water VGA cooler I may put on the single GTX, hopefully get some more out of it.
