I left room to crossfire it with a second 5770 in the future. I'm not sure if 650W is enough for that though. I'm also going to try and overclock it. If possible I'd like to drop the cost in a few places.
looks like a good system
I'm not a huge fan of Razor. Kinda overpriced (like Monster is for speaker wires). You could drop a couple of bucks w/ getting something from Logitech.
like WR2 said, you u wanna OC, you really should look at getting an aftermarket CPU cooler. Artic Cooling makes some inexpensive coolers that are cooler & quieter than stock
please dont spend 150 bucks on a mouse and keyboard, that can go towards your graphics card which (based on the card you provided) will bring your GPU budget up to $300. that means you can afford a 6950 which is MUCH better than a 5770 AND can be unlocked to a 6970.
also western digital > all
I'm on the boat with the other suggesters. Really since my last build I've decided that keyboard mouse aesthetics are useless, I use that budget money for my parts in my build more than the peripherals. Course the case has to look nice but I fit that into the budget just fine.
I will give you one advice. From 955 - 965 it is SO easy to get the 955 up to the 965's level. All you really have to do is go into BIOS and press + on the multiplier about 2 TIMES! Then you get a 3.6ghz 955. Well this all depends on the grade of your CPU. My 955 reached 3.6 easily stable with no need to up voltage.
Seriously though, It's cheaper and better for the price.
