Yup! I recently purchased an nVidia GTX 760, and now my Athlon 64 X2 5200 (2.6Ghz) has become quite the bottleneck! It only runs at 800MHz FSB. *shudder*
Here's what I've picked out;
ASUS Sabertooth 990FX R2.0
AMD FX-8350 Vishera 4.0GHz
Those are a combined price of about $400 at newegg.
It will eventually be water cooled, and overclocked.
Am I on the right track so I can start looking at how I'm going to cool it, or should I look at something else entirely?
