    Yes, as the non-Ti version is just an overclocked 460.
    Kalniel: "Nice review Tarinder - would it be possible to get a picture of the case when the components are installed (with the side off obviously)?"
    CAT-THE-FIFTH: "The Antec 300 is a case which has an understated and clean appearance which many people like. Not everyone is into e-peen looking computers which look like a cross between the imagination of a hyperactive 10 year old and a Frog."
    TKPeters: "Off to AVForum better Deal - £20+Vat for Free Shipping @ Scan"
    for all intents it seems to be the same card minus some gays name on it and a shielded cover ? with OEM added to it - GoNz0.

    Yes, sure. No, you won't see much of a performance decrease, but there is one.

    WTF? why did i say that?
    He needs the graphics card, i need the power supply for my new build.
    guess i'm thinking about too many builds in my head!
    anyway, we opted for a Asus directCU GTX 560 non Ti just to leave some head room for the PSU and for budget issues , should arrive in a couple of days

    Re: Is 450w PSU enough for GTX 560Ti?

    I wouldn't recommend it myself, you'll likely be putting the PSU under constant strain - increasing noise levels and thermals, as well as shortening the lifespan of the product.

    The PC spec looks pretty good for the most part, so I think you should invest in a slightly better PSU to match - rather than having an obvious bottleneck to your system. Should be able to pick up a branded 600W unit for ~£50.

    450 is just ok , but in your place would spend £40 for new one 600 or 750 ( in future can go sli or crossfire)
