I am hoping of building a PC but I don't have a massive amount of money to spend. In fact I have little money to spend. The plan is to get a Pentium G840/50 and a Powercolor HD6870 and upgrade the CPU when ivy bridge comes out (or maybe just buy a then cheaper quad core i5). I want to know if the pentium will bottleneck the hd6870. I play to play bf3, dirt 3(free coupon with card) and older dx9 RTS games. My monitor res is 1024x1280.
