    Hello All,

    I am looking to upgrade my iMac and MacBook Pro. (I don"t want to buy new yet)
    I already have a GPU:
    PNY Nvidia Quadro 4000 (2048 MB) (VCQ4000MACPB)
    Both machines have Thunderbolt/DisplayPort
    So I was thinking a Thunderbolt PCI caddy with 3 slots for a possible CPU upgrade later.
    Can anyone give me a best buy please?

    My computers specs are below.

    Cheers, Guy.

    Your 2010 iMac only has Mini DisplayPort, so it won't work with it at all. The early 2011 MBP has Thunderbolt, but only Thunderbolt 1 so it's hard to say if performance will be acceptable as that could definitely be a bottleneck.

    Yep as the other poster notes, the 2010 doesn't have thunderbolt so absolutely no use with that and the bandwidth on thunderbolt 1 will be lucky to give you more than 40-50% of the cards performance, even thunderbolt 2 at double the bandwidth won't get more than 80% performance out of an external card, thunderbolt 3 will make external graphics a decent option though.

    Thank you both for the heads up on Thunderbolt Display-port protocol, I wasn't aware of the difference.
    They are the same fitting though aren't they?

    Yeah same connector so that thunderbolt could also double as a mini display port, but thunderbolt wasn't released until 2011.
