I am also running two SAPPHIRE DUAL-X R9 280 3GB GDDR5 OC WITH BOOST (This is my 1st fully modular power supply, I have always used non-modular on the past) Head on over towards our AMD Radeon HD 7990.So i recently bought a new Power Supply,(Old Power Supply died) its an EVGA Supernova 1000 G2 80 Plus Gold Certified Modular Power Supply. In this review we'll look at the product, the architecture, the benchmarks, including frametime based FCAT measurements. AMD it doing it in style, two fully equipped Tahiti XT2 GPUs versus good yet silent cooling. The dual GPU product that you guys learned to know under codename Malta finally is released. We review the new AMD Radeon HD 7990 including FCAT frametime measurements. The new graphics card is intended to boost a little more performance into entry-level gaming. We test and review the MSI Radeon HD 7790 OC edition, also known under SKU code R7790-1GD5-OC incl FCAT Frametimes. The Gigabyte HD7790 OC 2GB clocks in at 1075 MHz on the boost engine, packed with totally silent custom cooling. We benchmark the product incl FCAT Frametimes. We test and review the Gigabyte Radeon HD 7790 2GB OC edition, also known under SKU code GV-R7790OC-2GD. But what about temperatures then you must be wondering ? That also means it's rather silent as it does not make any noise. This stock clocked Radeon HD 7850 is cooled passively, meaning it has no fans tool it down. We test and review the PowerColor Radeon HD 7850 SCS3 today. Here's how you connect three cards in CrossfireX mode. The advantage of a somewhat mainstream graphics card is that you'll only have one 6-pin power connector per card - obviously you'll need three of them. We use an unlocked engineering sample Core i7 870 processor and overclock it to roughly 3.75 GHz. We'll be testing on a new P55 motherboard today, this in fact is the eVGA P55 Classified 200 - yes the one with the gazillion PCIe slots. Let's have a look at the test setup we are using today. So you see there are many methods where two or more GPUs can be utilized to bring you a substantial gain in performance. Alternate Frame Rendering, each card will render a frame (even/uneven) or Split Frame Rendering, simply one GPU renders the upper or the lower part of the frame. There are multiple ways to manage two cards rendering one frame think of Supertiling, it's a popular form of rendering. if you are familiar with the hardware developments over the past couple of years you'll remember that 3dfx had a very familiar concept with the Voodoo 2 graphics cards series. Multi GPU rendering - the idea is not new at all. Then install/update drivers, after which most games can take advantage of the extra horsepower we just added into the system. Once we seat the similar graphics cards in the carefully selected motherboard we just bridge them together, with a supplied CrossfireX connector or in NVIDIA's case, a SLI connector. If your motherboard does not have the SLI certification mentioned on the box, it's not SLI compatible. A SLI certified motherboard is an nForce motherboard with more than two PCIe xc16 slots or a certified X58 or P55 motherboard.A Crossfire compatible mainboard is pretty much ANY mainboard with multiple PCIe x8 / x16 slots that is not an nForce motherboard.So along these lines, you could for example place two or more ATI graphics cards into a compatible mainboard, or two or more NVIDIA GeForce graphics cards in SLI mode. One card can do the job sufficiently, but with two or more you can achieve much more. As weird as that analogy sounds, that's roughly the same idea for graphics cards. One horse will get the job done yet by adding a second or third horse, you'll plough through that farmland much quicker and (hopefully) more efficiently. Think of a farmer with a plough and one horse. This way you effectively try to double, triple or even quadruple your raw rendering gaming performance. Multi-GPU gaming explained - Both NVIDIA's SLI and AMD ATI's Crossfire allow you to combine/add a second or even a third similar generation graphics card (or in more GPUs) to the one you already have in your PC.
