Err..no I've not checked to see if the memory is compatible but can't see why it shouldn't?
PSU is an antec tp-650 which I bought earlier this year when my previous 6 year old tagan 480w blew up and kicked the bucket. The above components also replace a heavily overclocked 754 pin sempron 3400, 1gb DDR RAM, 6800gt graphics, an obscure DVD reader which packed up years ago and a Hitachi 7k250 160gb hard drive so close to losing the will to live that at one point last year it had to place it in the fridge overnight to get it to work the next day! Even now I swear its responsible for the total retardedness of the performance.
In the past I admit I didn't take gigabyte seriously so never bought a product but recently became partial after learning they beat asus to win the mobo award last year with pc pro.
Incase u need to know I will rarely test the full performance of the pc but wanted something that will stand me in good stead for a while and really I'm bit of a benchmarker with the custom pc benchmark which is not synthetic based.
