Reccomend me a Graphics Card for Acer Aspire T120E

[GMC79]

Hi there, Need recomendations for Graphics card for my Acer Aspire T120E.
Recently had to get my pc fixed as it was totally knackered after a XP install failure, got it fixed now with XP pro, as new.
But now cant even run my Jimmy whites Cueball 2 or real one arcade, says i have no 3D hardware? Mayb graphics drivers not installed or working properly but installed them from Acer site with no joy.
I have 2gb Ram on the way and need graphics card to get MS filight sim and few simple games running again.
Something half decent and no more than £80 or so. What do people reccomend?

Acer Aspire, AMD Sempron 2Ghz/2Gb Ram (soon).
Think it's an AGP slot but unsure.

Thanks in Advance
GC.
