I multi task a lot as of now. Watching blue ray movies while doing video conversions,playing runescape. I mostly play kinda high demanding games. Mostly Battlefeild and Crysis. Other games as well. My current setup is the sandy bridge 2500 CPU, gigabyte mobo,16gb of ddr3 ram, SLI evga 550's. 1000 watt power supply, with a fresh clean install of windows 7 on an ssd (have other drives for storage ssd is only my os). Budget wise roughly $500 or so for a CPU and about $350ish for mobo. I still want to run SLI GPU
