    I have had a quick look online but you lot are more techy than me.

    I have been waiting for a while now for the new iMac's to come out and during this waiting it has made me wonder whether I should get a Mac at all, I play a lot of games (mainly on 360) and would like to play more on the PC. I know that the base iMacs atm can handle Skyrim and Battlefield but I'm thinking now that if I get a PC I can do all the stuff I can do on an iMac on a PC plus have the upgradability with graphics cards. The only problem there is I have never built a PC before and I kinow if I want a "gaming computer" it is best to build it myself to get more value for money, but I do want an iMac, so my main question is....

    Are there such things as external graphics cards, for example through Thunderbolt or not? Would be interesting to know, and it would swing me back to the apple side of my decision.

    IIRC there was a company working on an external GPU to attach via thunderbolt, but the only drivers are for Windows via bootcamp.

    There are some solutions coming this and next year, but current GPUs are loads faster than current TB technology can satisfy, thus there is no real benefit from using an external current GPU and getting more frames out of it.

    If you want to build your own computer, there are lots of guides and fora out there to teach you.

    Right now, the speed of external interfaces is to slow to make this useful. In a few years, possibly.

    Just built a PC on ebuyer,

    6 Core 3.3 Ghz Processor
    8GB Ram
    AMD Radeon 77701GB
    1TB HDD
    LiteOn Disc Drive

    All this plus delivery for £663.07

    As my name suggest I really don't know what to do anymore.

    If I bought an Imac do you think it will retain its value enough over the coming years to sell it and then put like £400 towards getting the next one which will then put me on a level playing field to play that generation of games?
