So I bought a plethora of new games in the Steam sale: Rainbow Six Vegas 2, GTAIV, Red Alert 3 and Stalker Clear Sky. So I downloaded the 15GB GTAIV only to find it sucks on my graphics card on fairly low settings. So unf. So I decided to try Clear Sky, that runs sketchily on very high settings (so why don't I turn the graphics down you ask? Because Clear Sky is supposed to look freakin awesome, that's why) so I've left that now. I installed RA3 and found it to be nowhere near as fun as I found RA2 when I first played that, sigh. So lastly I left Rainbow Six because it was getting late and I thought I'd probably have the same problems as the other two FPS-style games.

So blah. So many new games and I can't play any of them nicely. Makes me sad. Which means I'll have to go and buy a new graphics card, I've currently got a 7900GS (E6600 2.4GHz C2D CPU, 4GB RAM for other specs, so in those areas it s okay) as my graphics card which is pretty lowly and I was wondering if anyone knows of a decent card to upgrade to, preferably DX10 (I have Win7) and I'm looking at £150-200 because I don't think I'd get much better under £150 (and I'm a poor student, £200 is pushing it a lot).

So opinions and information please

There is some good news however! My good friend Philip who I know from #WebDev on dA bought me Machinarium for Christmas, which was terribly kind of him and I tell you what, it is freakin awesome, so good I'd recommend you buy it if you like point and click puzzle-esque games. It's hard to describe, but it looks pretty, interesting puzzles, requires some thinking, has decent music and such. So out of the 5 games I got over Christmas I love the one I got as a gift by far
