Ah right. I called apple about upgrading the graphics, I know its on a board, but I still thought the whole unit was swappable, apparently its not. I spoke with the support guy about how to improve my FPS in games he suggest I took my 1.5gb ram and make it 2gb. To be honest I have come to the conclusion imacs suck for gaming such as World of Warcraft. Yet I read a review that in Quake 4 on the 256mb you can get around 60FPS.
On world of warcraft I currently get 20-30FPS, apparently if you install windows xp on your machine using bootcamp from apple you can get around 45fps which is ok but not anything amazing.
After my motherboard on my pc decided to die on my the other night I was hoping I could just switch over to my mac and play games on that, it appears I am wrong.
It is shocking how such a powerful imac can lack in playing games, the intel 2ghz chip truely is amazing, my 1.5gb is amazing the graphics cards in the new imac, and old ones are still out dated quite abit but at least apple are putting in a little effort in the imac series to allow people to at least play games. Sometimes I wish I had bought a G5 normal mac, however there is only so much a person should spend on a apple product as my mac was £1300 anyway. So my mac sits here, rarely used. It truely is a shame.
