Ok I currently have a dell xps 625 and am finding that the current graphics card an ati radeon 4800 hd series cannot handle gaming very well anymore. I am looking to upgrade it but I am having trouble finding where to look for a compatible upgrade. I recently bought one on ebay and found out when i got it that it does not fit in my computer so I am an extreme novice when it comes to this.
Any advice would be appreciated, thanks.
