I have a Visiontek 4870 that I bought from Circuit City. I wanted to Xfire so I got another one off ebay at a good price. The seller says it's new and it was still in the plastic when I got it...everything was in place and didn't appear to have ever been opened. I've got them running now and everything appears to be normal, but the design of the two cards is significantly different. My first card is the typical 1-fan design that you'll find if you google an image of it. The one I got off ebay has two fans and a couple heat-pipes coming out the side, but the top of the shroud is labeled Radeon 4870 and the two fans are labeled ATI. Even the circuitry on the boards looks slightly different. The box it came from is identical to the box that I got my first Visiontek in. Is this a Visiontek card? Why are the two different? I just want to make sure I didn't get scammed.
When I look in CCC, it says the two cards are linked 8x which is expected on my P5Q-Deluxe...but it says the first card (the ebay card) has 256 MB of hyper memory, while the second card shows 512 MB GDDR5. The clock speeds are the same on both cards. Is this correct? Or should they both say 512 GDDR5?
I'm just making sure I didn't get ripped off. Thanks a bunch!
If your clock speeds are identical, and the Catalyst drivers allow you to run them in Crossfire, you must be fine. I don't think it will let you Crossfire two cards unless they're identical chipsets anyhow.
If you can get me a picture of the second card i might be able to tell if its a fake. Take the first visiontek you bought out of the case, Download GPU-Z and run it. This will give you a definite answer
They are both 4870's thats for sure, they are from the same Company. Its just that both cards are also diffrent. If you look closer at them. They only thing that is Diffrent is the Coverings and the Clocks, and the one from Ebay yes is better but not by much. With CrossFire enableing them the better of the two will really show its colors. I also have the same problem with my 8800GTS's one is from EVGA and Better one is From BFG. My BFG is better becase of the SLI will some how overclock my BFG and run my EVGA card at norm spec's. Don't Worry to much about it. If you want your computer to run them both at the same clock and speed switch Card 1 and 2 places. The Faster one will down clock to the slower one. One good thing about that is that it will run cooler.
