x1300 v. x1550 PRO

Hi guys!

My friend was asking about a few good PCI video cards, and I found these two, I'm not very good with the ATI cards (I can never follow the numbers)
So, can you guys help me out by telling me which card is better???
ATI X1300
ATI X1550 PRO
He told me that he would mainly be playing World of Warcraft and Halo PC.
Thanks!

the x1550 is the best PCI interface videocard you can get. However, this being said, your WoW would still have most of its fancy settings castrated.

What are the other specs of his computer?

I know it is a DELL.. bleh imo... Not sure of the model # (2400 i think) So, it's kind of oldish.
(Pretty sure of these specs)
2.3-2.6GhZ intel
1GB DDR (hes upgrading that)
350watt PSU
A normal, cheap motherboard that Dell uses

Thats about it..

I'd say there would be close to no point in adding more memory to that computer. If you have to buy a new videocard, get the x1550 and be done with upgrading that computer. Imho it is too old for upgrading.
