How do you find the C2D performing with modern system requirements? Do you have any slowdowns or experience any difficulties?
With the overclock, 98% of the day to day requirements are met with ease, the trouble comes with certain requirements that require more efficient and or modern compute horsepower, for example 1080p 60fps YouTube on chrome is right at the limit 100% utilization and a few hops and skips, however the on normal media players that's no issue.
Everything used for productivity runs fine, excluding things used to produce and edit audio and video, you can forget it, unless it utilizes the GPU.
Speaking of GPU its a 470 OC, the processor is the bottleneck in most games eg in Assetto Corsa all settings on low allows for 60fps with 100% Cpu utilization and 40% Gpu
Forget project cars or F1 2018, not possible
Overall you can use it, with the overclock, you'll be happy but the amount of things simply not possible are growing fast, its also very hot at 4.1 GHz.
PS GTA V no worries, bottle neck lies with the amount of VRAM on the GPU, I'm forced to Vsync at half ie 30 fps
