I want to play Crysis and GTA IV on a 1680x1050 resolution. Some benchmarks are showing the 4890 OC edition performs better and it also costs less. What do you guys think?

System Specs:

Case: Dell Vostro 200 case(getting thermaltake v9 black edition in about a month)
Motherboard: Foxconn G33MO2(getting ASUS P5Q Pro LGA 775 Intel P45 ATX Intel Motherboard in about a month)
Processor: Intell core 2 duo E8400 3.0ghz
Memory: 4gb PNY
Power Supply: Rosewill 630watts

Dollar for Dollar ATi makes the better card in my opinion at the moment, thou the nVidia still gives higher fps but slightly.

GTX280 will preform better in games where as other people have stated the 4890 will be more cheaper wise, the ATi is like a allrounder but the Nvidia is mostly a gaming style card.

4890 is the way to go it performs slightly less then the gtx280 for alot less money and can catch up by overclocking
I suggest you get the cheaper reference version and overclock it yourself.
