Speaking of the GeForce 7800 GTX 512MB, today’s stratospheric pricing on 512MB boards plays in CrossFire’s favor. If Radeon X1800 XT CrossFire boards are available at or near MSRP, you could pickup a Radeon X1800 XT CrossFire card for about $150 less than the GeForce 7800 GTX 512MB. The savings magnify when you factor in the cost of SLI versus CrossFire with a Radeon X1800 XT CrossFire setup costing roughly $1200, while a GeForce 7800 GTX 512MB will run you about $1500. Of course, considering ATI’s track record when it comes to availability, the million-dollar question everyone wants to know is how much will Radeon X1800 CrossFire ultimately cards sell for at retail? If supply is low and demand is high, history has shown that e-tailers will quickly markup the product, a $650 or $700 pricetag isn’t unreasonable. After all this is currently what’s happening to the GeForce 7800 GTX 512MB, as street prices on boards start about $100 over NVIDIA’s $650 MSRP for the GeForce 7800 GTX 512MB.
