upgrade?

[pull2808]

looking at possibly upgrading my graphics card as currently mines not the best (radeon x1300/1550). Its from a dell inspiron (bad i know) but the general info people seem to ask for are:

Core 2 duo E550
2 gb ram
Res: 1440*900

Basically would like to know what i could upgrade to without upgrading anything else (psu)?

Budget of around £50 - 80.

Thanks
