What video card can i put in my gateway 2610s



Apparently that model has a 275W PSU and a PCI-Express x16 slot.

The HD 4650 has a minimum 400W recommendation. I think it's too risky on a PSU rated 275W.

Consider a HD 4550 instead. That one has 4 times fewer stream processors than the HD 4650 but should still be better than the integrated video you had. It has a 300W recommendation. Still risky but less.

Edit: the second one (Gigabyte) has DDR3, while the XFX has DDR2. I'd pick the Gigabyte.
