Hello and welcome to the forums
As others said it depends on what you do with your PC.
i7 750 wins in multi-threaded apps like some games which benefit from Quadcore and some apps(like PhotoShop) but in non multi-threaded apps i5 630 performs better
I would go with I5-750. It wins on all scenarios: Games, Heavy Apllications, etc.
And now with DirectX 11 games will use better the multithreading capabilities, if avaiable. The i5 dual-core is just too expensive.

Thanks for all your replies!
I was going to use it for gaming and maybe a bit of Photoshop.
Generally speaking for a Lower end system it will cost you more, BUT you will have controll over the QUALITY of parts. Brand names generally will skimp on PSU, Memory, MB and GPUs. The PSU will meet the system requirement, but not offer much headroom and the quality is generally middle of the road. Your NOT going to get a Corsair PSU with that "store" bought Computer!!! Memory will normally be the cheapest they can get - ie High CL ratings, and the smallest size modules. If you decide to swap out memory you will normally have to replace all installed memory rather than just add to it. MB features may not satify current and future needs. Bios' is often "locked" which prevents some needed/desired changes. The GPU's are often "lowest contract" price than can find.
As to saving money. The only time I've been able to "Save" is when comparing "High-end Systems. BUT as to the Lower-to-midrange systems the extra COST is well worth it.
