I'm on a budget of about ~£330. I know there is no current GPU, Will be buying a second-hand GTX 275, And Win7 HP.
Anything else I forgot to add? And how is the build at this price? Currently stands at £327.
(I have a HDD already)
I would strongly recommend stretching your budget for an i5-2500k (with a decent cooler) as you will get MUCH better performance for a slightly smaller price. I know you have a crunched budget, but something to shoot for.
The PEntium G680 performs as well as the 2100, get it. Use the savings to get a better graphics card. Please fill out the form entitled "How to ask for new build advice" sticked at the top of the forum
