When I first got the computer, it was a Dell Inspiron 531s. I am no longer in the slim case, and looking to replace the last 3 components that makes it a Dell. The Hard Drives, the OS, the PSU, and the Video Card have been replaced last year. This year I'm wanting to upgrade the last 3 pieces and wanting to take full advantage of my GPU. My current PSU: newegg.com/Product/Product.aspx?Item=N82E16817341019&cm_re=OCZ700SXS-_-17-341-019-_-Product My Current Video Card: newegg.com/Product/Product.aspx?Item=N82E16814150447&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-RSSDailyDeals-_-na-_-na&AID=10521304&PID=3463938&SID= My case: Was given to me, so I have no link for it as it didn't have any markings on it for the make/model of it. HDD: Sata Drives, forget the make & model of them, but there are 2 of them in RAID 1 (Mirror, think that's RAID 1) mode. Looking for a very reliable motherboard, cpu & ram for a budget of around 250-350. My current setup is being bottlenecked by the cpu (it's too slow) and would like to take full advantage of my video card. Also, the mobo needs to have RAID 1 (Mirror) support. I will be running Windows 7 Ultimate 64-bit. EDIT: Also, I'm not planning on buying until I get my Tax Refund, so mid-Feb, early March is when I am planning on buying.
