I'm looking to upgrade my PC. Overall, I'm happy with it's performance, but I've been getting a lot of micro-stuttering in games. I currently have an i7-930 OC'd to 4.02ghz, and 2 HD 5770's in crossfire. From what I've been reading in the articles on the site, it seems I should upgrade to a single HD 7970 first to see the biggest improvement. Also, from what I've been reading, going to a i7-3770k really wouldn't be that much of an improvement at all.
