£730($1200) Gaming pc build

Hello there, I put up a thread a while back now which was also about building a budget gaming pc but just recently I have now got up to £730 or $1200 to spend on the build. This build will be mainly for gaming and rendering, I would like to have some room later on for upgrading, so I got a full tower and oversized the psu.

Here is the parts I'm thinking of getting if anyone else can come up with something better that would very helpful thanks.

I know this thread is a few days old but i'm feeling generous today :D (that doesnt stop me being lazy)

I would recommend shopping around a bit at the following list of places;

Ebuyer.com- generally cheap

Aria.co.uk- nice psu selection/cheap hdd's

Overclockers.co.uk- usually good deals on mobo's/gpu's

Dabs.com- occasionally have great offers on gpu's


i have purchased parts from all of the above (excluding dabs) and they all offer great sutomer service

I hope you didn't make this build :( for the money you could have a much better configuration!

For example - (Didnt spend much time looking at mobo but you can get a decent 1 for around the same price)
