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.
I'm using an ati radeon HD 4650 with a dell but it keeps screwing up! any help?
Thanks everyone for your input. My grandsons system is as follows:
Machine name: B0882CE586B9459
Operating System: Windows XP Professional (5.1, Build 2600) Service Pack 3 (2600.xpsp_sp3_gdr.090804-1435)
Language: English (Regional Setting: English)
System Manufactuerer: Dell Inc
System Model: Vostro 200
BIOS: Pheonix - AwardBIOS v6.00PG
Processor: Genuine Intel(R) CPU 2140 @ 1.60GHz (2 CPUs)
Memory: 3070MB RAM
Page File: 611MB used, 3834MB available
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?
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; http://www.newegg.com/Product/Product.aspx?Item=N82E168...
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.
