Seems like a good system! I'd recommend a Samsung SSD for $15 more as it'll be faster but the choice is yours. Everything else seems fine though as you've allowed yourself plenty of room for future upgrades.
Haha, I was waiting for someone to notice the MB being wrong for SLI! :P I only reaslised today that it was cross-fire ready and not SLI ready so I bought a new MB today ( ASUS P8Z77-V LK Motherboard). I'm still trying to get SLI to work as it's not accepting my current screens :S
I'll be looking into better PSU's but now I am happy, cheers for the comment!
Thanks! I plan to get a see-through side panel on the case so I can have myself a window but before I do that, I want the cables looking neat.
The RAM upgrade will be happening in the future when I have more money (currently broke) :P
And I love the screens, thanks for the comment!
