Hello,
I am purchasing the following pc from PC specialist:
Intel E6400 2.13GHZ
2GB Corsair DD2 677
320GB HDD
Asus 680i Sli Motherboard
500W PSU
Now the problem i am having is graphics, i can either put in 2 X 512MB 7900GS and run them in Sli, or i can have one DX10 320MB 8800GTS. I am in to hardcore gaming so which would be the best choice?, also would 500w be enough for two 7900Gs?
Thanks!

It doesn't list the 320mb version but the 640mb stuffs the sli 7900gs by some 30fps in Half Life2 add to that the fact you can use DX10. I think it's a no-brainer.

If you go down the Vista route in the future then DX10.

Good point - DX10 only runs under Vista.

Yeah i have a copy of vista ultimate ready to put on it?.
So the 8800 is better regardless of the difference?
8800=500mhz/1600mhz 320mb
2x7900GS 900mhz/2640mhz 1024mb
Or doesnt Sli work like that?
Thanks

you don't get twice the performnce of the single card, sometimes you don't even get the performance of the single card!
Check out Tom's Hardware reviews, and don't forget you can always Sli the 8800 when money allows. It's your call but I would go for the 8800, it's a good match for your cpu and games like Crysis will take advantage of the DX10 of your card and the core 2 duo processor.

ok then, i have decided to og with the 8800, but is 500w enough for two of those?. I read somewhere that the 640MB version consumes no more than 115w on load, so the 320MB version must be about 100w i presume.

the gpu is the same so I would think the power requirements are the same. Hard to say if 500w would be enough, it depends on the quality of the psu - it's not just the watts, it's how many amps it can deliver under load. Go for a decent make and you should'nt have a problem with 500w.

Ok thanks a lot for your help guys.

you can also do some very naughty things with your E6400 as well!
