Comp specs are
6 gb Corsair Dominator 1600mhz
i can play games like BFBC 2 and stuff max graphics, but then some games, like ARMA II it struggles. I dont know if its my cpu, or my graphics card bottle necking the system.
Would it be stupid to upgrade the process and card? I guess is what im really asking lol.
is right: the best (true) upgrade you can make is waiting up until LGA2011 launches...what you need to do is identify the actually cause(s) - it could be hardware, software or both issues that may need addressing. But as everyone here is suggesting, provide concrete details of your system.
Core i7 LGA 1366 is still the go to platform for most enthusiast...i7-920 is loved by many (even I, though I've never owned one, yet I'm budgeting for a Core i5 2500K Sandy Bridge Build).
