Tbh, I'm a little perplexed, why not just get the i3

?
For his uses, frankly most chips will be overkill, I'd probably just get ;
http://www.overclockers.co.uk/showproduct.php?prodid=CP-497-IN&groupid=701&catid=6&subcat=567 and try and squeeze an SSD in.
Those CPU's are incredible bank per buck, for board you could go ;

And we're talking tiny money here.
Or
http://www.overclockers.co.uk/showproduct.php?prodid=MB-483-GI&groupid=701&catid=5&subcat=2803 this would definately allow an SSD in the build, and handle web use and minimal apps, although the weakest of the lot performance wise.
On the AMD side, the FX's start off at more money ;
http://www.overclockers.co.uk/showproduct.php?prodid=CP-339-AM&groupid=701&catid=1967&subcat=1825 but this is a better CPU than the Pent all in.
And then any AM3+ board
And an equivalent priced AMD's CPU ;

But on the CPU side it's no where near the pentium.
Any FM2/+ board that takes your fancy.
And I can't see any Kabini stuff on OCUK, which would also be fine.
Basically, anything you buy would be fine

, I was just perplexed about "I have budget for i3, but I'm on a budget" lol
