As you can see I am gunu use it as a gaming pc would anyone recommend other parts instead of those above, my max spend is around £875 and this is with the operating system which isn't above. (the above costs around £720)
Welcome to the forum. I would drop the 2500K or the H67 chipset, and change to either a P67/Z68 or plain 2500 (not unlocked) or lower. Also, you may want to dedicate a little more of the money towards a higher end GPU, depending on your resolution. Also, if you choose not to overclock that aftermarket HSF won't be necessary. And yes, you most likely won't require a discrete sound card.
Thanks for the comments, I have taken away the sound card, put the intel i5 to 2500 and replaced the motherboard with the P67. Also got the CX400w PSU and reduced the RAM to 4gb But I'm stuck on what GPU would be good for around 200 - 250? thanks
It seems like a lot of people are recommending GeForce 560 or 560 Ti for around that price. I'm shopping for one too so I don't really have a solid recommendation. If I were you, I would decide on the GPU and let that dictate what PSU you get. Figure out the minimum recommended wattage for the GPU and maybe add 50 or 100W just for good measure. For instance, the 560 ti recommends a 500W minimum.
^+1. If you want Nvidia then a 560TI would be nice, otherwise maybe a 6950. That's a tad over your budget though so you may have to look at a 6870 instead. It would also probably be best to get a more powerful PSU as eight said.
Is there a difference between a zotact Geoforce GTX 470 and the Winfast GTX 470?
There might be a clock speed difference or something. Look at the specs. Most of the time, there isn't a practical difference between brands (as long as the specs on the cards are the same). You should look at reviews though. Some specific brands or cards have issues which should be reflected in their reviews.
