I don't really see the point going for the corsair supply when there is alternatives from the likes of Antec do the job for less money, they are gold certified and arguably better units.
why not go for something of a lower power output that suits a single GPU system better.
for example

this is an excellent supply and in my opinion, better suited to a single gpu system than a HX850 or XFX supply.
16gb ram is the max for win7 home no? a 256gb sd would be sweet, but then we'd probably need to make savings from elsewhere like case and heatsink etcthis presents a saving that could go towards something more exciting like increased memory capacity, case mods or even a capacity increase on the SSD
Cool, I will stick with silver arrow heat sink. Thanks for the tip on RAM. Has the 680 gone up on here? Thought there was one for £384? Might compromise with an i5 3570 and a 680.
