What kind of PSU do you have? List the model or all the specifications AND the brand.

You need to open up your case and take a picture of the sticker. Upload it to www.imageshack.us and make sure to select 'do not resize' option. That should give me more than enough info.

Also, you need to tell us how much you're willing to spend to upgrade your PC.

Your power supply can't drive neither GTX 550 Ti, nor HD 5770/6770. Your best choice at 100 euros would be HD 7750. It costs around 95-105 euros, at least in my country (I live in Europe too).

I am afraid your budget is too low for upgrading power supply, so I didn't suggest you that.

Yes, but how in the performance it will work the HD 7750? :)  do it will be slower then GTX 550 ti? or HD 5770? :)

Your power supply is too weak for gts 450. It's also slower than HD7750.
