Build check :D

Okay made a few posts a month or so ago, got a good reply or two, but a few friends have given me some advice and I'm going to build it myself now, so changed the specs I was using, heres what I got so far

Intel 3rd Generation Core i5-3570K CPU - 74
Asus P8Z77-V LX Motherboard - 87
G-Skill 8GBXL Ripjaws X for Intel Sandybridge Platforms DDR3 PC12800 1600MHz 8GB Kit - 49
WD Caviar Green 2TB Internal Hard Drive - 73
Asus HD 7770 2GB AMD Radeon Graphics Card - 122
Corsair CX750 Builder Series CX 750W ATX/EPS 80 PLUS Bronze PSU - 71
Cooler Master HAF XM USB 3.0 E ATX Case - 95

All prices are GBP

few things to note, first yes, the case is friken huge, but I saw it in a shop and fell in love with it :p

Building it for gaming and uni work over the next 4- 6years, (Big case plenty of room to upgrade in future)

I've got left over lolly, is it worth getting a second graphic card?

Is the G-skill alright? they come as two 4gb

Also I'm looking for a Optical drive, so far I can spend a bit more so Im looking at a blue ray one over a normal one any suggestions?

Anything else I need? or is there anything I can upgrade for a smaller / medium amount on that list

(Windows 8 preinstalled btw + again, monitors mouse keyboard speakers are being bought seperate)

Cheers :D
