Just my personal opinion Rox, but I'd stay away from asus boards, I had lots of trouble with my last one. Now using the gigabyte ga-z77-ds3h. Supports sata 3, usb 3, has a suitable slot for your gfx card, runs rock solid and overclocks just as easily as the asus. Team that with an I5 processor (make sure it's a 'k' series if you want to overclock - sandybridge is the 2500k, newer ivybridge is the 3570k). I'd also consider at least one new hdd, 7 years plus is quite a good age if you're using the machine regularly.
