To those who want more details about my computer; it is a Gateway DX4850 with a Core i5-2300 Quad-Core 2.8GHz processor, 6GB of RAM, 1.5TB of hard-drive space and an ATI-Raedon HD 4600 graphics card. The wired control was for the 360. If you need anything else, just let me know.
Are you sure your GPU is specifically a HD 4600, not another model in the HD 4600 series?
It's hard to find specs and information about the HD 4600 because it's quite old doesn't appear on many contemporary GPU hierarchy charts, but from what little I could find apparently it has a 3DMark benchmark score of only 850 - for comparison, my mid level GPU has a score of 4680 while a high end GPU has a score of over 9000 [http://community.futuremark.com/hardware/gpu/ATI+Radeon+HD+4600/review].
I think the GPU could be bottlenecking your system, because while your processor and RAM meets the minimum system requirements, because the GPU is underpowered the control issues you're experiencing is probably just input lag... it's taking some time for the GPU to process and display any actions you're performing.
Google results seem to indicate that the Gateway DX4850 isn't really meant for gaming, it's more of a multimedia computer that lacks the power supply to support a more demanding graphics card (300W isn't really enough for gaming), so short of replacing the PSU and GPU you could try turning down all the graphics settings in Skyrim to the minimum and see whether that makes it run more smoothly.
Another possible explanation for your controller issues could be that your computer's 300W PSU is really being pushed to the limit by Skyrim (especially if your GPU isn't the low end HD 4600, but a more powerful contemporary model in the 4600 series), so plugging in a wired controller which also draws power could be the straw that broke the camel's back.
Also, what does Can You Run It? [http://www.systemrequirementslab.com/cyri/intro.aspx] say when you check the system requirements for Skyrim on your computer? That site is quite a good indicator of how well your computer can run a game, as well as highlighting any weak link that may prevent good performance.
