Yep he's planning to get SSD soon , looking at m4 curcial 128gb
As for the PSU , i myself have the same PSU on this build
i7 920
EX58-UD3R
6GB DDR3 Triple Channel
HD 6870
the rig is 3+ years old now , all working good (the 6780 is less than a year old , had a 9800gtx+)
all the parts were bought locally (Oman) so there weren't many options for PSU
Thanks all for the replies
