Hi All:
I want to know the difference between Ati Radeon HD 4870 CrossFire or Single ? Crossfire is what the graphics are better or vice versa? I think that the graphics do not depend on the crossfire, but the software with which you shall have them. what you say ?
Thank you
Crossfire and single both are at their best moments, which are really rare, like 170% of the original power. Reason 2: The two cards wouldn't even be better than a card costing as much as them, even if they would both perform at full power. Make sure you have a powerful enough power supply for the new card.
Selection should be in favor Of radeon HD 4870 X2 . because Not all motherboard are coupled with Full high speed PCI- E ports , even some motherboards (which advertise CrossFireX support with 16X) can\'t function correctly with such configuration . The cost of two radeon HD 4870 is today higher than one Radeon HD 4870 X2. Moreover we note also the higher energy consumption in IDLE regime for the pair radeon HD 4870 in CrossFireX.
Speaking now about Radeon HD 4870 X2 2 x 1Gb CrossFireX , first , besides the high cost of those card , they require a powerful power unit with at least 850 watts and above. Second : the performance is usually limited by the processor . Today the overclocked processors ( by ~34% ) Intel core 2 Quad QX9650 was insufficient for the complete satisfaction of radeon HD 4870 X2 CrossFireX appetites even in the qualitative regimes (with AA and AF). The only exception are Crysis and S.T.A.L.K.E.R.: Clear sky.
