CooltechZone claims that ATI's R520 will follow NVIDIA's GeForce 7800 GTX (G70) example, this means that the cards will be available worldwide on the date of launch:
"According to an insider, ATI is aware of NVIDIA’s strategy and knows the negative impact it could have on its corporate image and financial position if it tried to do another paper launch. The insider reported that ATI could’ve released its R520 at Computex (or even when NVIDIA announced its G70 GPU), if it intended. But one of the key reasons for waiting until August (hopefully) is that it wants to make sure the cards are available for purchase exactly when the R520 core is introduced. Therefore, you can expect the availability of the R520 to be immediate."
Yesterday we also reported that prices of NVIDIA GeForce 7800 GTX are falling towards the $550 range and that they will soon hit the $500 mark. The upcoming GeForce 7800 GT will possibly retail for as low as $399.
