I will be running Maya/3ds max, Photoshop / Dreamweaver / Flash, C++, and the gaming with my pals.
Here is what I'm considering putting together, please comment and give me some honest opinions about this. I'm not finalized on my decisions yet.
Processor: i7 2.8 930
Proc cooler: v8 Cooler master
Mobo: Asus p6x58D premium
Memory: CORSAIR CL8 12 gigs (6 X 2gig sticks)
PSU: OCZTECH gold 850w ATX
GPU: EVGA GTX 470 ( I know a place that has it in stock right now)
I already have a custom painted HAF932 and 2 7200 RPM HDD's along with Windows 7 64bit Pro.
It's not a bad build, but there are some components that are overkill for this type of build. The v8 cooler doesn't have much more than its looks going for it. The Hyper 212+ cools better for much cheaper. The P6X58D Premium is also quite overpriced for what it offers. Are you trying to leave the option of SLI open? If not, you could go with a considerably cheaper motherboard and PSU. Here's some components to consider that won't negatively effect the performance of the system, but will save you a good chunk of change.
I may go SLI eventually, not right away but I would like to keep that option open for the next couple years. The memory and heat sink can knock a few bucks off and seem like pretty good suggestions. I don't want to under power my rig by only going with 600. The GTX 470 wants a minimum of a 550watt PSU. go ahead and correct me if im wrong but it just seems like im cutting it close.
I suggested the 600W PSU for a single GPU setup. You can stick with the 850W PSU if you're trying to leave the option of SLI open. Just keep in mind that SLI will only improve gaming performance. 3D applications can't utilize SLI. The cheaper Gigabyte motherboard I suggested is still a good option since it supports SLI.
