Summary: Well, where do I start? This has been a very impressive board from Gigabyte. It has the looks and the brains. And it certainly isn’t short on features. When this new line of AMD motherboards came out there seemed to be the impression that it really wasn’t going to offer too much over the previous chipset. To be honest this new chipset itself doesn’t offer a whole lot over the previous generation. Yes, you do get SLI support and dual-channel DDR3 support.
Conclusion: In many respects, the Gigabyte GA-990FXA-UD7 is similar to competing AM3+ boards. But with its support for up to four-way SLI and CrossFireX, it’s an excellent choice if you plan to build an extreme gaming PC that’s stacked to the max with high-end graphics cards.
Pros: Loaded with PCI Express x16 slots, Supports CrossFireX and SLI, Supports up to 10 SATA 6Gbps drives
Summary: The overall performance of the GIGABYTE 990FXA-UD7 wasn’t far off the competitor today. What really sold us on the GIGABYTE 990FXA-UD7 was the overclocking! We have previously been unable to POST past 4.6GHz on our AMD FX-8150, on the GIGABYTE 990FXA-UD7 we were able to boot into Windows 7 at 4.9GHz with all of the cores active!
Conclusion: First off, the easy part – benchmarks across the board were indicative that both of these boards are 990FX / SB950 chipset boards. There’s just no reason to think one will out-do the other when benchmarking. The UD7 shows that it is as capable a 990FX board as the Crosshair V. So, that leads us to the differences. Looks? It’s personal preference of course. I really like the way the UD7 looks and if a decision between the two came down to that, the UD7 would get my vote.
Conclusion: Gigabyte is putting significant store in AMD's new FX chips by releasing seven 9-series boards armed with the AM3+ socket. The headline act is the 990FXA-UD7, which is a £200 board designed with the enthusiast firmly in mind. Presented in an eATX form factor and well-laid-out for a genuinely high-end offering, the UD7 can run four double-slot graphics cards for ultimate performance.
Summary: They say everyone makes mistakes. When I think of the Gigabyte 990FXA-UD7 I realize that truer words were never spoken. From start to finish my time with the 990FXA-UD7 was miserable. I just wanted the experience to end but with all the problems, working with the board took far longer than it should have. It is without a doubt one of the worst motherboards I’ve ever worked with.
Summary: Every once in awhile you come across a motherboard that raises the bar on what an enthusiast board should be. It sets the standard for features and performance exceeding all your expectations. This type of board forces every board you see from that point to meet a higher standard in order to impress you. The Gigabyte 990FXA-UD7 is not one of those boards.
Conclusion: As expected the latest AMD 990FX/SB950 shows no significant performance gain over the last generation chipset from AMD (890FX/SB850). The new chipset is essentially identical except it offers native support for Bulldozer and NVIDIA SLI. While we are disappointed that there is not a major update to the new chipset, especially with the lack of native USB 3.0, we are at least glad to see that AMD still continues with its backward compatibility support.
