So any advice will be appreciated, do you think the PSU is all good for this system? Will i need to purchase a better cooling system if i decide to do a little overclocking of the CPU? nothing major though, and ill probably end up sourcing myself some G Skill RAM its just they dont sell it on this particular site.

Thanks a lot guys.

Oh, yes, and would this PSU be fine if at some point i decided to go Crossfire with my GPU?

don't double post, just edit your first post

first off everything's gonna work nicely together, but if you're gonna add a second 6870 in the future I'd recommend getting like a better model 800w PSU to be safe. It says on newegg that crossfire uses 600w which is a generous amount, but with an overclocked 2500k it wouldn't hurt to have a bit more power.

with the PSU the earthwatt brand is entry level for antec so it isn't the best for a powerful build, it'll do fine with a single card, but I wouldn't trust over $1000 of hardware and a crossfire setup to it. Corsair TX-850 850W ATX Power Supply, 140mm Fan, Dual PCI-E Graphics Card Connector, 8x SATA Connectors, Universal AC Input 90~264V [CMPSU-850TXAU] - $213.06 : AlphaCity.co.nz, NZ Super Online Store, Laptop, Computer Parts, Netbook, Graphic Card, Cas something like that is a bit more expensive, but would be a lot more solid in the long run, especially if you wanna add new components, or feel like upgrading the mobo/proc down the line.
