Whats the best video card for WOW

Tell us more about the rest of your system. Wrath of the Liche king is pretty intensive, much more so than before this expansion.

Tell us your resolution, CPU, motherboard, ram, OS, PSU and the kind of performance you'd like to have.

just one video card:

EVGA e-geforce 9800 gx2 SSC edition!
amazing! absolutly the best videocard i've ever seen.
...i'm not sure but probably someone in e.bay is selling yet this card at e good price!
bye!

There are definately better cards, but it might be good for him under the right circumstances. Please let us know your current system and desires before running out to get the card above.

if you only intend to play wow then any mid range card will be fine, but keep in mind that wow is pretty CPU intensive, so i'd suggest that you get hold of a decent CPU instead of spending hundreds of pounds upgrading your Graphics card.

hope this helped.

Thanks everyone for your input. My grandsons system is as follows:

The 4650 would be find for running WoW. Looks like CPU is the issue. You might need to crank down the settings. As Micheal said, it can be a CPU intensive game.
Someone with more experience might be able to comment, the Vostro most likely came with a 300W PSU, is that enough to power the 4650?

A 46x0 would do ok but may suffer under any high res setup. I would consider a higher end card as well look on ebay and newegg for better deals.

Yeah, your motherboard should be able to handle better processors. Even something cheap like an E5200($60) would be a large upgrade over your current CPU.

Thanks everyone! I think I'll check out that duel core 5200? I think it will do the trick!

Considering you can't OC on a Dell this would actually be the better choice as it is clocked sightly faster and is almost the same price;

Make sure you upgrade to the latest BIOS from the Dell website before upgrading. That one isn't on the upgrade list they have but it is likely just because it is a new version of the processor. Other wolfdale chips are listed so it should be fine.

Thanks!
