[shotgun king]

this will be my second build Ive done and i wanted to do something a little more flashy i guess you could say.I have been playing bc2 quite a bit the past few weeks and even with everything on low its still quite laggy.I am wanting to keep keep my ECS Black Series A785GM-M mobo since i bout it only a year ago.just bought a NZXT M59 Gaming Mid-T Case and soon to purchase a Noctua heatsink (seeing that it will fit).currently have 2x2gb of 800mhz ddr2 ram that i may move to my backup system (all my old stuff) and a cheap 1gb ecs gpu.any ideas on a good amd processor ram advice gpu (to handle bc2) or anything else to help?money really isnt an issue just nothing too outrageous like $200 for ram.

I'm not 100% positive as to what you're asking. But I've read enough to tell that you have an older system.

It would be a better idea to buy a new system entirely instead of building around an old motherboard.

really just wanting to build a new system that can handle more complex games at mid to hi graphics without lag.the motherboard can go into my backup system just didnt want to waste a good board.dont know much about H/T speeds L1 2 and 3 cache and things of that sort to make a good system.I do have a AMD athelon II 3x 435 Processor...not sure if its the best in the world for gaming but wouldnt mind keeping it if its good for it.
