In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 240 PowerColor OC V2 2GB Edition are marginally better than the AMD Radeon R7 240 2GB.

The R7 240 has a 20 MHz higher core clock speed and the same number of Texture Mapping Units as the R7 240. This results in the R7 240 providing 0.4 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 240 has a 20 MHz higher core clock speed than the R7 240 and the same number of Render Output Units. This results in the R7 240 providing 0.2 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

Both the Radeon R7 240 PowerColor OC V2 2GB Edition and the Radeon R7 240 2GB were released at the same time, so are likely to be quite similar.

The Radeon R7 240 PowerColor OC V2 2GB Edition and the Radeon R7 240 2GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the Radeon R7 240 PowerColor OC V2 2GB Edition and the Radeon R7 240 2GB are the same, which means the R7 240 and the R7 240 have equal limitations when it comes to graphical data transfer.

Both the Radeon R7 240 PowerColor OC V2 2GB Edition and the Radeon R7 240 2GB have 320 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the R7 240 has 0.4 GTexel/s better Texture Fill Rate and 0.2 GPixel/s better Pixel Fill Rate, but the has GB/sec greater memory bandwidth. Although the GPUs are very similar in performance, the R7 240 takes the edge.

The Radeon R7 240 PowerColor OC V2 2GB Edition requires 30 Watts to run and the Radeon R7 240 2GB requires 30 Watts. We would recommend a PSU with at least 400 Watts for the R7 240 and a PSU with at least 400 Watts for the R7 240. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
