There is no difference between a server and a consumer CPU as far as desktop use goes.
They can both work under hot conditions and they both (in this case) heat up considerably.
The Xeon E3-1280 v2 is severely overpriced at 660$.
You might as well grab a Core i7 4930K.
Also, if you want a CPU that's significantly faster than your current one, I suggest you grab the Core i7 4930K.
But, if you're upgrading from the Core i5 3450, you're not going to notice much of a difference.
