While both are now about seven years old, in terms of computation, the recycling center's 3rd Gen "Ivy Bridge
" Core i5-3350P CPU (and mainboard?) clearly wins over the 2nd Gen "SandyBridge
" Pentium G630 (4 cores instead of 2, PCIe 3.0 vs 2.0, faster memory addressing - with matching RAM - and thanks to more cache):https://ark.intel.com/compare/69114,53483https://www.cpubenchmark.net/compare/Intel-i5-3350P-vs-Intel-Pentium-G630/1109vs1476
Note, however, that the 'P' in "i5-3350P" indicates "processor only, no on-die video chipset", i.e. this one will have to be used with a dedicated graphics card. This said, almost any dedicated graphics cards from the past seven years will do better than what's integrated into the G630 (Intel HD Graphics (GT1)
, execution units: 6, boost clock: 1000 MHz, max GFLOPS: 96).
I'm not certain these are the Nvidia ones Titi recommended (I'm not so much into Nvidia, prefer AMD/ATI due to their open Linux drivers), but based on their release dates they may be, and this gives a clear picture:https://www.videocardbenchmark.net/compare/Intel-HD-Family-vs-GeForce-GT-730-vs-GeForce-GTX-750/37vs2906vs2825
