Performance gain will be negligible... some people say Win 7 "feels" faster... but so far as I know most benchmarks are showing it to be on par with Vista. You'll more performance out of newer hardware than you will out of a newer OS.

------------------------------ Desktop: Windows 7 Professional 64-bit; Intel Q6600 CPU; E-VGA 780i SLI motherboard; E-VGA E-GeForce 8800GT; OCZ Vista 4GB dual-channel kit; Ultra X2 750W power supply; 2 x Seagate Barracuda 7200.11 500GB in RAID 0. Laptop: Acer Aspire 8730-6314;

Responsiveness in general use is improved but don't expect to see framerates increase by anything noticeable.

Then what if you were to install Windows 7 onto a older Vista PC that never really performed all that great with Vista.

Would it have a noticeable improvement in performance compared to having Vista installed? (Lower Boot times, more responsiveness)

Depends on the specs of the computer.

For boot times and responsiveness, 7 is definitely faster than Vista, but don't expect gaming or any sort of CPU intensive task (video encoding, etc) to be any faster.

Yeah, I think my laptop is a lot faster, but it's basically a very similar OS. feels faster I should probably say. Same drivers for both so I wouldn't imagine performance would be much different. It sure loads a heck of a lot faster. Yeah I'd say responsive too.

I think the big difference will be newer technologies will be optimized for Win7, like SSD's and DirectX11.

SSDs are definitely better on Win 7. I also agree that the boot time is noticeably shorter, but I am more pleased with the fact that I can start Firefox within 5 seconds of the desktop showing instead of 1 minute.

In Vista I've noticed a lot of HDD activity in the first few minutes after booting up. I don't see that in Windows 7 at all. Wonder what Vista was doing to my drives ><

Superfetch is what the HDD thrashing was. Win 7 uses a much less aggressive form of Superfetch.

Once DX11 is in full effect, both Vista and W7 will benefit, so there wont be a huge advantage in gaming. Theyve setup a more paralellised usge in W7 in 2D that allows for faster 2D usage, and is why its snappier, as having several apps , when cued, dont have to wait when mulitasking, as more than 1 is actually being able to process at a time

I would like to see a similar test being made on a Netbook with total focus on productivity, witch I think is more interesting than testing Windows on a super rip. I think, if Windows 7 have speed advantages it will be more obvious on a slower computer, and on a rig that Windows 7 claims to have advantages on
