Pegatron 2ac2 Motherboard Bios Update

Please help!! I I am not very savvy when it comes to hardware. I have a HP Pavilion P7-1110, i3 2120 cpu, 6gb Ram, 250W psu, and a Pegatron 2ac2 mother board, with intergrated Intel HD Graphics. I play World of Warcraft and have had no issues playing the game until the Legion xpac. I need to upgrade my graphics and need to know what cards are compatible with this system. I have a budget of $150.00. I do not need to play the game on ultra setting (although it would be nice) just want the graphics to run smoothly, lag is a killer during pvp.
Thanks for taking the time to help.

Dec 05, 2010 Hi guys, After updating the BIOS on my crappy HP computer, the CPU fan constantly speeds up once every one or two minutes. HP wouldn't help, the only way is to order their replacement motherboard, they said.
