Final compatibility/ improvements on build

[Terrifiedrelic]

This is what I am planning on getting for my new build. It would primarily be used for gaming at 1080p. I would like to be my parts from http://www.mwave.com.au as I live in Australia, and as far as I am aware it is the best bet. Please tell me if any parts are incompatible, or if you think I should be getting any different parts. I will be making do with an old hard drive until prices come down. Budget is $750-$800. I would like to crossfire in the future. I will buy cooling for overclocking later.

Thank you for any assistance

Quality of Cooler Master PSU is questionable - Antec, Corsair, SeaSonic, and XFX have good track records.

Antec EA-650 650W Green Power Supply - ATX / EPS - Cooling Fan - Active PFC - 80 PLUS Bronze - SLI & CrossFireX Ready Certified - Green

Will you be getting CPU cooler (since you got a CPU begging to be overclocked)?

If so, the tall heatsinks on the Corsair RAM may pose a problem as large CPU coolers can block RAM slots.

Would that psu be ok if I wanted to add another gpu in crossfire later? Also do you think this RAM would be better

I will get cooling when budget allows. Any advice regarding the 6870 vs 6950?
Thanks

Yes, that RAM is better. Yes, a quality 650W will be able to power two 6870s or 6950s. But, I would consider a 750-850W for more headroom.

Of course, go with the 6950 if your budget allows it.
