Flipping back the other direction, we know Grid 2 to especially tax a system’s memory subsystem. But because all of these configurations employ DDR3 memory at 1600 MT/s and a GeForce GTX Titan, we can be certain that the big performance swings are a result of swapping CPUs in and out.
The Pentium’s average frame rate jumps more than 20% due to overclocking, while the tuned Athlon is a little over 10% quicker. Intel’s Core i3-4330 is barely faster. The Core i5 enjoys a greater margin, though at significant expense.

Looking at the frame rates over time nicely illustrates the impact of cores, clock rate, and architectural differences.

Much credit goes to Nvidia’s GeForce GTX Titan graphics card, but frame time variance is remarkably low across the board. In the sample over time, AMD’s Athlon X4 750K stands out most prominently in orange, and it does encounter a handful of spikes. However, the 95th percentile figure is still a scant 3 ms.

dont buy a pc so cheap you cant cool it or have a good motherboard.
When the i3 is £90 and can be put in a cheap (£40) H81 motherboard without needing the effort of finding a stable overclock it seems a bit risky to go for the Pentium.
However, if a later upgrade to an i5K or i7K is planned (or you need the Z series chipset features) then the Pentium is a good way to start saving towards that upgrade while not compromising on the expense of an i3 or drop in performance of a regular Pentium.

Anything above 4.3Ghz wasn't stable, even with the voltage up to 1.34v (not prepared to try higher than that as temps were too high). This was likely down to the cheap mobo, but I'm not going to complain about that, as it's still a nice overclock for the money.
