Onboard ATI 2100 or ATI 9500 GT PCIe

[enic]

Hello,
Just upgraded my motherboard/cpu (Athlon X3 455) and wondered if the onboard ATI2100 is better worse than a ATI 9500GT PCIe card that was in my old system.

Aiming to buy Radeon HD 5770 in a month but wanted to know which to use until then.

An ATI2100 isn't much of a motherboard upgrade? The nVidia 9500GT is much better.
