Can this machine run games like Super Smash Bros. Melee/Brawl at 1080p?

Just from my personal experience, my i5-2500K does great with LLE on thread (that wasn't the case until a certain revision came along) and I haven't even OCed it yet. Using LLE fixes Melee's audio issues, and it doesn't seem to demand all that much more from my CPU, as opposed to HLE audio. Other games that require LLE (Tales of Symphonia and Skies of Arcadia are the only two I've dumped that need it so far) run at full-speed, and my CPU usage isn't maxed out either. I'd recommend an i5-2500K, but if you got that, looks like you'd need a new motherboard too, since you're using an AMD chip right now.
