I would like to spend around 500-700$$$
How is this for a complete build:Athlon II x4 620
: $99Gigabyte MA770T-UD3P
: $70 after $10 MIR4Gb DDR3 1033
: $100HIS 5770
: $153 after $10 instant promo code 'VGA1214'Antec 300 Illusion Case
: $55OCZ ModXStream 500w PSU
: $40 after $25 MIRWD Black 1Tb Hard Drive
: $100Sony Optiarc 24x DVD/RW
Total: $649 after $35 in MIR's and a $10 promo code
This will give you a quite fast and high quality build that you will be able to upgrade as needed in the future.
If you want to shave a bit of the costs, look into the following componets:Athlon II x2 240
-OR-Athlon II x3 425
: $774Gb DDR3 1066
: $75 after $25 MIRWD Blue 500Gb Hard Drive
This will bring the price down to $461 or $480, after MIR's, and will still be a massive upgrade from your current system.
