It's the same price before MIR and has free shipping. It's a higher quality unit that's 80+ Bronze certified and has a 5 year warranty. It also puts out more power on the 12v rail than the 700W OCZ PSU and has enough power connectors to power two 5850's without adapters.
If he has intentions on Crossfiring his 5850's which he says he might, I wouldn't hold out on the PSU unless you're willing to buy another later, which would waste money. You can get a 750W Thermaltake or Antec for 30 dollars more than what you're suggesting. Well worth it.
There's more to building a rig than meeting minimum requirements too. This guy's throwing around 1100 dollars to buy 6 things because he has the rest already, including a Blu-ray player etc. See his monitor? He's got money. He's going to need more than 650W in the future, I guarantee it. He'll end up crossfiring, perhaps with 5870's who knows. Running RAID, anything. 30 dollars now or a pain in the future? 30 dollars.
That Antec looks nice. I guess it pretty much comes down to which PSU. Well, I'm going to leave the PSU purchase till the end. Hopefully I find an awesome deal on the PSUs you guys recommended.
So everything else is fine, that's good to hear. Any opinions on the motherboard? This will be the first time I use ASRock. I just really like it because of the features to price ratio and the reviews on Newegg seem promising.
The motherboard should work. I always stick to either Gigabyte or Asus, but you shouldn't have any problems with that board. ASRock is the budget division of Asus. The quality of components used isn't up to Asus and Gigabyte boards, but it's not horrible.
