I have that 8600GT, works gr8 and can play CoD4, Fallout 3, CS:S, Hl2, so most of the older games but less newer games.
I would recommend a 4670: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127383
Gr8 power and you dont need any extra pci-e power connectors to the 4670, just plug it in and should work with ur 300W PSU. This is my best suggestion, and it runs in the new ATi architecture. 512 MB, 128-bit, 320 stream processors, your best card.
Other recommendations, read this article (and look how the 4670 did) : http://techreport.com/articles.x/15559
Above I'm a proud Gran Turismo fan, not a Sony fanboy, and now a proud 360 owner, but sharing xbox live accts ATM
End of 2009 Predictions (made Jan 1, 2009): My predictions were pretty accurate, the 360 was over and the Wii was just under.
Wii: 65 mil (yea I'm crazy) 360: 35 mil (its getting there) PS3: 30 mil (the slim better do well)
End of 2010 Predictions (made Jan 7, 2010):
Wii: 81 mil 360: 47 mil PS3: 45 mil
