After reading a fair amount of reviews, I think I have settled on a Radeon HD 5670 as a graphics upgrade for my Dell Inspiron 530. This seems to be a good card to pair with a Dell 24" monitor to play Starcraft 2. I am thinking of getting the SAPPHIRE 100287VGAL Radeon HD 5670 (Redwood) 512MB 128-bit DDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card.
I don't want to upgrade my power supply, and it looks like I should be fine in that regard. But here's my question- the PCIe slot in the Dell is 1.0. My concern about this card is the following - I know that there is backward compatibility and PCIe 2.0 should be fine, but it sounds like some have had problems with an HD5670 PCIe 2.1 card in a 1.0 slot. This card says it is version 2.0, but there seems to be conflicting information as to whether any Radeon 5670 cards are actually 2.0 or whether they are all actually version 2.1.
So what do others think, will I be OK with this particular HD5670 card in my computer? I can't find any other Radeon 5670 cards that say they are 2.0, so that is my reason for deciding on the Sapphire card. Thanks!
