just want to know what i can all update to run my games (crysis, cod5, etc.) for the time being. i still might go with a whole new

computer later, that's why i am looking at the gtx 260 for 219.99.

i dont know how the 260 will work with all the rest of my components though. or would it be better to get a 9800 gtx instead. im either getting a gtx 260 or the 9800 gtx and im wondering if my cpu will bottleneck the gtx 260, becuase i want to play crysis and cod5 with plenty of fps so..... help!! thanksComputer update help?
The CPU will bottleneck the 260. Well, the CPU on that motherboard, anyway.

Either upgrade the lot, or just go for a 9800GTX and a better power supply, and save the money for a complete upgrade later.
