Advice on a card for under £100 and 32 or 64 bit

Hi,

I recently upgraded to win 7 on a Nforce 2 board and have had a load of prob's (as posted on here) its seems that my old NF2 board can't run Win 7 so I have now treated my self to a new pc (comming for xmas) spec as here;

WIN 7 32 or 64 bit?
Asus M4A78-VM - DDR2 1200x2 780G chipset
AM3 Phenom X2 250 3.0 GHz,
4Gb Corsair Memory DDR2 1066 (2x2Gb)
500GB SATA Hard Drive
Cool Master 500W PSU

Can anyone please recomend a graphics card (pci-e 2) for under £100 that would suit this set up (either ATI or Nvidia) its main use is for internet with the odd games play but its not really intended as a gamming pc.

Also should I install 32 bit or 64 bit Win 7 ?

Any help please

If gaming isn't a concern you could save the £100 and just use the onboard HD3200. If you still want a card at the top end of your budget something like this,

Sapphire HD 5750 1GB GDDR5 Dual DVI HDMI Display Port Out PCI-E Graphics Card - Ebuyer

for a middle of the road option,

Sapphire HD 4670 512MB GDDR3 DVI VGA HDMI PCI-E Graphics Card With Free Collectors ATI Ruby Figurine While Stocks Last - Ebuyer

Stormy13,

Thanks for your help, I am not sure how good the on-board graphics are thats why I was thinking of having a pci e card fitted, also as I understand it having a card fitted will free up some of the ram and run a little smoother.
