XFX Radeon HD 5770

I'm looking at getting a 5770. However, I particularly like XFX's products. I'm looking at 2 of their 5770's and have one question, What's the difference? Besides the cheaper one being PCIe 2, and the pricier one being PCIe 2.1, there seems to be no performance differences. But I do like the 2.1, because it's smaller, and it will allow for more airflow in my Lian-Li PC-Q08 case. Would it be worth the extra $20 more for the smaller one, since it would give me the performance and airflow in my case, or should I get the cheaper one?

PCIe 2:
PCIe 2.1:

System specs:

Mobo: ASUS M4A88T-I Deluxe
PSU: OCZ Fatal1ty 550W
CPU: AMD Phenom II X2 560 (Unlocked to X4. Yay!)
RAM: Mushkin DDR3 SODIMM 1333MHz 8GB (2x4GB0
Current GPU: XFX Radeon HD 4770

Also, little side question. I couldn't find out online, but what X4 model does the X2 560 unlock to?

  1. AFAIK, there's no difference in speed between the 2.0 and 2.1 specs, and obviously both are compatible with current PCIe slots.

    If you're concerned about air flow, have you considered getting a card that pushes some hot air out of the case instead of inside it?
  2. Get the 2.1 Lives up to the same specs of the cheaper one it doesn't have a negative it's only more positive since it's a single slot card.
  3. Single slot cards are generally hotter.Get the normal version.
  4. Agree, single slot card can really get hot pretty fast when gaming/full load. I also suggest you take normal card(dual slot).

  6. So it would be wiser to get the dual slot? Also I was thinking that it might be a good idea cause there is a vent a the bottom of the case which looks like a dual slot card with a fan could pull air from outside.
