The ATI Radeon 5XXX Thread

9800gx2 128SPX2 Core Clock 600 MHz Shader Clock:1500
GTX280 240SP Core Clock 600 Mhz Shader Clock:1300

5870 1600SP Core Clock 850 Mhz

5870 should beat 4870X2 without doubt.

Not so fast. Keep in mind, the 4870 had the SPs and TMUs increased by 2.5x over the 3870, and it isn't even twice as fast the great majority of the time. 4870 to 5870 is only a 2.0x increase.

I think a nice 550watt corsair would handle a single 5870 just fine, even with overclocking on the cpu, gpu, ram and all your peripherals. I wouldn't count on getting a second card for xfire though.

I have no doubt you could easily run a single 5870 on a 300W PSU. No way it would draw anywhere near that from the wall.
