Advice on a graphics card?

I have had to buy a new desktop as the hard drive in my old one (2002 vintage) was on the verge of giving up (again); and as I use it for business as well as FS9, it was time for a replacement.
My new one is a better basic spec than the old one (Intel dual core 2.2/1.4Ghz processors, 2Mb fast SDRAM, 250Gb hard drive, WinXP) but only onboard Nvidia 7050 graphics which are almost useless as far as FS9 is concerned - decent frames in clear skies only! I'm in no real rush as my new laptop runs FS9 better than my old machine did(!) - however, in an ideal world, what kind of graphics card would anyone recommend for this spec of machine? I'm looking at running FS9, not FSX.
Thanks!
