So, I've come up with these parts so far :

CPU Intel Core i3 2120 Dual Core Hyperthreading Processor LGA1155 3.3GHZ Sandy Bridge 3MB - price match newegg.ca $124.99

MOTHERBOARD MSI Z77A-G43 ATX LGA1155 Z77 DDR3 2PCI-E16 1PCI-E1 3PCI SATA3 DVI HDMI VGA DX11 USB3.0 Motherboard $119.99

PSU Corsair VX550W 550W ATX 12V 41A 24PIN ATX Power Supply Active PFC 120MM Fan $59.99

HDD Western Digital Caviar Blue 500GB 16MB Cache 7200RPM 3.5IN SATA Internal Hard Drive OEM $74.99

CASE Antec One Mid-Tower Gaming ATX Case Black 3X5.25 5X3.5 2X2.5 Front USB3.0 Top Rear 120MM Fans No PSU $47.99

Optical drive ASUS DRW-24B1ST 24X SATA DVD Writer OEM Black- ncix $17.99

Total 769.33 ( after taxes and shipping would be free because of the PSU promotion or I could actually pick them up in local.)

1. Could you check if they compatible each other?
2. Would that GPU enough for games like Diablo3, LoL, SC2, Wow at its max settings?
3. Would that PSU enough for my system?
4. Is there alternative mobo I can look up? I'm hoping to use this system for the next 2~3 years.. So, upgradable mobo would be nice
5. Would that GPU fit into my case/mobo since it has 3 fans

I've spent so many days to absorb these knowledge on each part and brands etc since I'm huge nub lol. But i'm willing to learn here. Please help this newbie for the first time building GOOOD pc!

Thanks a lot for reading this long thread and looking forward to hear from you, experts! ;)
