Why not replace the motherboard and reinstall your operating system? It wouldn't cost too much more ($50-$60 for motherboard and $20-40 for the heatsink/fan combo) and you would be able to have the possibility of overclocking potential!
You would need to find out what kind of RAM you have in your current system so you could swap it into a compatible replacement board (probably an mATX form factor due to it being a Dell) Is this link pretty close to your system specifications?

I personally own
this Gigabyte GA-73VM-S2 (mATX form factor) board and have overclocked my E6750 to 3.0Ghz on it by merely upping the FSB value just using the stock Intel HSF with decent temperatures. I know it's a deactivated item but it was just an example.
When I bought that board it was only $54.99 and you could pair a similar board at a similar price with a cost-effective cooler like the
Xigmatek HDT-S1293 reviewed here at Legit Reviews.com and
on Newegg.com
For $37 it doesn't get too much better than that!
Or for a cheaper route the
If you wanted a cheaper route you could go with the
$22.99 Xigmatek HDT-SD964 cooler, but it's a bit smaller and not as efficient, but with Mail In Rebate it would only cost you $13 when all is said and done!
Just some suggestions for you!
***Looking over that spec sheet, you would most likely want to just chuck that RAM anyway and upgrade to a stick of DDR2 667 or DDR2 800 for about $9-$15) since DDR is outdated and finding an LGA 775 motherboard with DDR wouldn't exactly be easy or cost-effective***
