how later do you plan on upgrading to bulldozer and 6970? cause it might almost be worthwhile to just skip the hd 6850 and go with onboard, though it depends on what games you plan to play. Or you could just start out 6970 and save $160.
I get $40 off if I buy a 965 with a AM3/AM3+ mobo at microcenter and 955 is only 5 dollars less than a 965 and they don't have it at microcenter. Also, I'm thinking of getting a ModXStream 600W version for 6850 crossfire. What do you think?
I want to know if there's a part where I can cut down and get a better case because HAF912 looks ugly to me.
You did a really fine job coming up with a good gamer for the price you set for yourself. I have the HAF 912 case. It's a bit 'musular' looking but a really well made case. If you can get it for $55, you won't be dissappointed. Most cases in that price range are made of quite thin metal and have no cable management at all. Not so with the HAF 912. Btw, your HD 6850 link opens to an HD 6870 @ $200.
My one concern is the split rail power supply. Unless the 2 +12V rails can be combined, you may want to switch that for a similar single rail PSU. I believe the HD 6850 or 6870 may max out the current capacity of an individual rail @ 18A. Not positive on that, you may want to double check. I have always opted for a single rail PSU in my builds just because of the graphics cards current draw when maxed out. Overall, you will have a very capable gaming machine. Remember, in gaming... it's all about the graphics card.
