So My computer is an Acer Aspire AX3400-E2202 Some specs..
OS: Windows 7 home 64bit Processor: AMD Athalon II X2 215 Processor (2 CPUs), ~2.7GHz Memory: 4096MB RAM HDD: 582GB
Video Card: NVIDIA GeForce 9200 Approx. Total Memory: 1903
Basically, I really want to be able to play Starcraft 2, and right now it is too laggy for my comfort. But my issue is I don't want to spend a lot on this because I'm not a big PC gamer. I guess the bigger issue is the fact that my pc is TINY and my power supply is only 220w. PLEASE HELP
