The motherboard you have is a good one. Gigabyte makes some pretty good boards and are priced nicely too.
If you plan on SLIing then make sure what ever PSU you choose is SLI certified. Of al the reviews i've read on PSU's between 500w and 600w Hiper seams to be the brand with the best overall reviews on Newegg. Not to mention they are modular. Thats just my oppinion though. http://www.newegg.com/Product/Product.asp?Item=N82E1681...
Do your research. I would recomend a PSU over 500w. I went all over the place pricing and reading reviews of powersupplys. Newegg was an exalent resource.
yeah, i wouldnt recommend it. The Hiper PSU's are made to look good.
I'm in australia so I'm having trouble finding a few of the brands they recommended, and the price difference is a little ouch-worthy. I figure I can probably go up to $140AUD ish though. Is the Enermax one ok?
I was also looking at the Antec TruePower 2 550W, but the one im looking at on ebay is actually 12mths old so im not sure if I should even go there.
Well, for me, the ultimate cooling solution as far as air circulation is concerned is when you can have fans drawing air INTO a case through the lower front and the side and EXPELLING air out the top and upper back. With that in mind, finding a case that meets most or all of those requirements or has the potential (through modding) is always ideal.
