First Build Advice (£800-£900)

Hey guys I'm looking to build my first rig in the next month or so (summer holidays) and just wanted to get some general advice as to what you all think of an initial mock up.

While I remember I also want to note the current price of the parts listed is as near as makes no difference £900, so please don't adjust anything that increases the price without trade offs, unless it's very important, as the current mock up is already a big stretch in terms of budget.

I mainly want to ask what people think about the MSI motherboard, since I heard the support from MSI is terrible, and I don't know if I'm better with alternatives around a similar price? Basically, I'm just not sold on a motherboard that has "gaming" in the name, and suggests it's a but gimmicky and might not last.

I was originally looking at a 760 but I decided I could probably stretch to a 770 if thats a good choice? I've heard good things about Asus and their 770 being made if high quality components

I have picked Windows 8 and I know lots of people hate its guts but I've gotten to grips with it on my laptop so if anyones going to complain about the aesthetics of 8 or user friendliness then that won't affect my decision. Of course performance or incompatibility can easily sway me but I heard 8 does actually have a slight performance boost over 7.



Aside from that theres some general info below about the budget and such.


The budget is around the £800 mark up to £900 (around $1400-$1500 in US $ if thats easier) but I wouldn't like to go over £900 as it's quite a push as it is.

This is a gaming PC primarily as I have a laptop for general word processing but I would hope the rig would be pretty versatile.

I'm from the UK so please keep that in mind but aside from just trying to find an equivalent part in Britain I don't see why this would be an issue.

I'm not currently looking ti overclock but I like the option, hence the i5 4670K. Also, its unlikely I'll be running SLI anytime soon. I don't need the performance boost and it isn't viable un my price range anyway.

Thanks and sorry for the long post, most of its probably useless but better than giving no context whatsoever.
