More RAM Or Video Card For Game Performance?

Hi,

I've got a 2.13GHz Core 2 Duo, 1GB Dual Channel DDR2, PNY 7900GT (256MB RAM) and I want to upgrade for better gaming performance. Nothing's overclocked.

My question is, should I go up to 2GB RAM or add another 7900GT and go SLI?

I can get the RAM for about $175 or the video card for about $225. My power supply is already good to go for SLI.

I was fairly happy with my machine's performance running FEAR and Ghost Recon - just occasional stutters with most settings pretty high. However, Flight Simulator X on high is causing a lot of stutters and slow frame rates. When it stutters, the hard drive light is on solid or flashing.

Any suggestions, recommendations or opinions are greatly appreciated!

Thanks,

Jake

I reckon getting sli wouldnt be the best way to spend your money. Get another gb of ram which will help you with all applications not just games. The 7900GT is still new and should run all new games maxed out. When you do upgrade youll be better off jumping straight to a DX10 card in the futur
