I,ve got a laptop (gateway nv59) with 4 gig ram, i3-330m and radeon hd5650 gpu. I want to built myself a cheap gaming (civ 5, diablo 3)desktop. Would I notice any difference in performance if I choose to go with an i3 3220 and radeon 7770 in my desktop ?
The newer Ivy Bridge i3-3220 is not only clocked higher than the 1st gen mobile i3 CPU, but it can also process more instructions every clock cycle which makes the i3-3220 much more powerful.
Mobile graphic cards are much weaker than the desktop version. The mobile Radeon HD 5650m would probably be equal to a desktop Radeon HD 5550. In any case, the desktop Radeon HD 7770 is a significant increase in performance.
Honestly I doubt you need more than what you have for Diablo 3.It runs smoothly.
I would still upgrade the desktop to save the laptop lifespan.Gaming in Laptops is quite bad for the machine,components heat up and its hard to get air in to cool it.
You could check your temperatures with HWInfo, maybe your laptop has been invaded by dust bunnies and heatsinks are no longer able to do their job so the CPU/GPU end up overheating and throttling themselves.
A fresh reinstall every now and then can help with removing all the junk some programs might leave behind over time. If you do not mind having to re-install and patch everything, it may be worth trying.
I would recommend installing on a spare HDD so you can easily restore your current install if the re-install does not yield expected results.
The spare drive install strategy is just my personal preference.
That way, if I need to do something before I am done installing everything on the new copy, I can switch to the old install and continue the new one later.
If you install to your only available drive, you have to finish installing all your frequently used stuff before you can go back to normal. It usually takes me a couple of days before I stop running into things I forgot to re-install.
