7800gt sli upgrade question

[uB3rn00b3r]

I currently have a amd x2 3800, 2gb of ram, and a 7800gt. I just purchased one of the westinghouse 22 inch monitors on black friday and its native res is 1680 by 1050 and my card seems to be struggling at that high of reslolution in games like company of heroes. I was wondering if picking up another 7800gt on ebay for about 100 dollars would be a good idea for playing at my monitors native res. Im hoping this will hold me off until I do a major upgrade next summer for dx10. Is it a good idea or are there better options.

For $100, I'd say go for it and do a bigger upgrade down the road. I am running SLI 7800 GTs and I am hoping to wait till next Dec before I build a whole new box.

I am playing Company of Heroes as well, I can't play on top settings but I think it looks good as I have it now. Fun game, even though those damn Krauts keep owning me.

if you don't need bleeding-edge graphics technology, then go for the second 7800 GT. however, you'll be (at best) a generation and a half (8800 -> 7900 -> 7800) behind. depending how you look at it, that might not be so bad.

From what ive read it seems that the benefits of SLI really start to kick in at higher resolutions, like 1680/1050 on my monitor. Is this true? I definitley wont have a lot of cash until I can get a decent job before I head off to college this coming summer.

so 7800gt would be better for me running at a high resolution then selling my card and getting say a 1900xt?
