256 bit 1 gb GDDR5 HD 5750 or 128 bit GDDR5 Hd 7770?

I'm a bit torn between these two card. They both fit my budget, but I'm unsure which card would perform better. The only place that offers a 256 bit variation of the HD 5750 is tigerdirect- http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5566524&sku=V261-5750

I was uneasy since I've never seen a 256 bit 5750, so I email customer service and had confirmation that the info was correct.

SO, I'm wondering if the older 256 bit 5750 would out perform the newer 128 bit 7770?

  1. 7770 of course. Much newer card, better features. 128 bit is ok with this level of performance.

    All right, thank you! Glad to finally have that cleared up.
  3. The Radeon HD 7770 is almost as powerful as a Radeon HD 5830. I would guess-timate about 90% of the HD 5830's performance.

    I'd get THIS CARD:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814102993

    It runs at 1100MHz (most at 1000MHz) and costs $115 (after MIR) but has free shipping.

    Sapphire is also a great company for quality.

    *Also, learn to use the free tool RadeonPro for:
    a) forcing VSYNC when unsupported in a game (i.e. Witcher #1, drag the "witcher.exe" file into RadeonPro and enable VSYNC.. )

    b) forcing Anti-Aliasing when unsupported in a game (ME1, however in the case of ME1 I'd use SuperSampling instead of MSAA. More costly but worth it.)

    It has other features but those are the main two. The CCC (Catalyst Control Panel) may offer some of this functionality though I'm not up to date on that (NVidia now).
  5. ^CCC allows u to force both anit aliasing and vsync as well as anisotrohic filtering and other features that are not supported in some games.
