As for the build, some suggestions -
Get this CPU + RAM combo
X3 445 + Mushkin 4GB DDR3 - The Tri-Core would be a good option for a gaming PC IMO...http://www.newegg.ca/Product/ComboDealDetails.aspx?ItemList=Combo.514579
Graphics card - I would suggest this one -
EVGA GTX 460 - Might cost just a bit more than the HD 5770, but offers performance comparable to the HD 5830...http://www.newegg.ca/Product/Product.aspx?Item=N82E16814130562
