I'll overclock the i5 to 3.2Ghz w/ turbo - if you have any suggestion, keep that in consideration!
Someone suggested this mobo: ASUS P7P55D-E PRO

Case: Since I’m no more going for a C/F build, I gues it’s a good idea to change of case. I have to admit I have zero knowledge about this.

***I made this build ~1 month ago, I was really going to buy these pieces, but I heard USB 3 was coming & 6Gb mobo too so I decided to wait until I go back to school. Now I'm not sure if it's again the good time to buy a system, but I need one =S***

My old router died, I need a new one.
Do you have any suggestion? I don't really use wireless connection, but I looks like wireless routers are cheaper ?!

I just checked for the 5850 (I was wondering if the price changed) and it is now at 308$. I noticed that some model have higher frequency (and higher price). I gues that these card are pre-overlocked and I am wondering if I can do it myself instead of paying 30+$ for one!
