Vista - no problem, just need help deciding.

hi everyone

soz about title didn't know what to write

i have an acer 5735z (european) and recently reinstalled vista. performance has slowed down on gaming and aero performance. i have givin up on trying to find the fault and am now considering buying a graphics card. i am a kid so am waiting until christmas and ma birthday to get money. i reckon my budget would be £150 to £200. any recommendations? have been lookin at nvidia and amd and lookin the like of the ati radeon and geforce series.

GTX275 if your PSU is up to the task that is

no no :P HD4890! haha wait.... Christmas......... lets wait and see what the HD5000 series will cost, also a 275 is roughly equal to a 4890, but the 4890 uses less power

when i said was lookin in nvidia, i did look at the gtx series. i don't care if one uses more power or not, i keep my lappy plugged in at all times! and i don't pay electricity bills lol
i haven't heard of the HD4890 or HD5000
if the hd5000 costs over £250 i will go to the gtx275
how can i tell if my psu (does psu mean Power Supply Unit?)is up to it? do you need a certain voltage?
thing is, where can i buy the card? are there any markets i could go to in dorset to see the card? if not, it is trial and error buying online.
