I carried an 8kg dell pc to China and its fucking shit; "HDTV" VD/BBT episodes wont even play (5fps) and streaming is so-so too. need to buy parts for a custom build.

im wondering what kind of spec is capable of SC2?
RAM?
CPU?
GFX?

prices are cheaper in china...e.g. AMD Athlon II X4 631 = 50quid (70quid on ebay). Is this cpu any good?
AMD phenom II X4 970 = 89quid

halp

edit: 250-300 budget

For lolz...my current spec:

P4 2GHz
1GB RAM
Intel 82845G gfx
