If you don't plan on overclocking I would personally go with the Xeon. Similiar or cheaper price and you get hyperthreading.
The "similar or cheaper price" is nonsense. Those Xeons cost approximately the same as their Core i7-counterparts, and significantly more than any Core i5. For that reason, they are only a viable alternative to a Core i7.

Thanks for your replies guys. So I guess it's the i5 for gaming. But what about the temperatures? Do you think the i5 will be much hotter than the Xeon?
I'm worried about that after looking at the TDPs of both. Xeon has a lower 69W TDP and the i5 has 84W.
I do not know where your numbers are coming from. The Haswell-based Xeon CPUs have a TDP of 80-84W. Your 69W are simply wrong (unless you got those from some sort of outdated Xeon from an earlier chip generation, which you hopefully do not plan on buying).
dannylivesforher :
So do you think it will cause much of a temperature rise in the i5?
No. All these chips can and do go up to 100°C when under maximum load. Not that maximum load ever occurred except in dedicated torture tests like the one Prime95 does.
With the i5, not using the internal graphics means you can use its thermal budget for the CPU. With the Xeon, you do not have an integrated graphics in the first place. The result is the same. The advantage of the Xeon is slightly larger CPU cache in exchange for the missing graphics. But again, the Xeon is an alternative to the i7, not to the i5 (based on prices).
