I had an XFX GeForce 9800GT 512MB PV-T98G-YDLH, but it started to have some serious issues (artifacts + BSoD) and I sent it back to XFX. They issued a replacement card of "equal-or-greater" value/performance, but I feel like the card I got may be of neither equal nor greater value: XFX Radeon HD 5670 512MB HD-567x-YNF3.
I can't find any reviews where I can easily compare the two cards head to head, but looking at their specs it seems that the HD 5670 might be a little better when it comes to numbers. The only thing that concerns me is that the memory bus on the 9800GT is 256 while the HD 5670 is only 128 bit:
Bus Type: PCI-E 2.0 GPU Clock: 600 Mhz Memory Bus: 256 Memory Type: DDR3 Memory Size: 512 MB Memory Speed: 1800 Mhz Thermal Solution: FANSINK Minimum Power Supply Requirement: 350 Watt Outputs: HDTV, , Dual-Link DVI
Radeon HD 5670
Bus Type: PCI-E 2.1 GPU Clock: 775 Mhz Memory Bus: 128 Memory Type: DDR5 Memory Size: 512 MB Memory Speed: 4000 Mhz Thermal Solution: FANSINK Minimum Power Supply Requirement: 400 Watt Outputs: HDMI, Dual-Link DVI, Display Port
I'm not very up to date on the new video cards, so given the above specs:
The Radeon seems superior in all other aspects, but how much impact does the 128-bit memory bus have on performance?
Does anybody have any links for real-world performance of the two cards that can tell me if the HD 5670 is in fact equal-or-greater value/performance?
Should I ask XFX to give me a different card, or is this a "fair trade?"
