Help choosing the right CPU from Xeon or i7 Desktop Series

I'm building another system with Intel Core i7-3770K with ASUS P8Z77-V Deluxe motherboard.
I came across Intel Xeon E3 1275 V2 CPU which I liked very much due to its advanced technologies over the i7-3770K but the xeon is missing Intel Insider & Intel Wireless Display Technology which I might find usefull afterwards.

Q1]Is the mentioned xeon cpu supported on Z77 Chipset? if yes,then is it recommended? [price difference is about 10$ to 15$]
[I am programmer and I play games sometimes although I would be getting a 2 GTX Titans soon for heavy gaming ;-)]

Q2]Or should I wait for the i7-4770K be released in May-June?

Q1 - The Intel Xeon is not supported on the Z77 chipset, also Intel Xeon are targeted for servers, workstations so a i7 would be better for gaming.
Q2 - There is not much performance increase on the Haswell processors (4th Gen Intel), so you are better of just getting the 3770k, the 4770k will only give about 5-15% increase of performance to the 3770k.

Just now I was searching for xeon support on Z77 chipset and found some people who have a working xeon in a Z77 chipset but I thought it is not possible but it seems though! Could you just check it out?

If performance increase is just about 5 to 15% then there's no point in buying i7-4770K processor, I just considered it 'cause it has HD Graphics 4600 which is 10 to 50% faster than HD Graphics 4000.
But if the Haswell CPU has soldered backplate rather than low quality integrated heat spreader used in the i7-3770K then might it be any good in terms of overclocking ability? [Not looking forward to any overclocking over 4.2GHz]

from what i've hard the non OC performance is a bit like sandy to ivy.but it was going to be exccelent for overclocking.

If you absolutely cannot wait, get the 3770k. With Haswell being so close, I would just wait. Intel doesn't tend to lower CPU prices on old products so a 4770k will be about the same as a 3770k. For example, a 2500k and a 3570k are only about $5 apart in price.

I could wait until some news on the heat spreader technique used in the Haswell processor arrives, if Intel still uses the same low quality heat spreader on it then I would get the i7-3770K before i7-4770K is released.

I was hoping to get the mentioned xeon processor but as it turns out its not supported on Z77 Chipset [Officially], if only there were a gaming/workstation combo motherboard supporting Xeon E3 series CPUs... :(

Low quality heat spreader? :??:  BTW, Haswell is supposed to use less power than Ivy.

I said that 'cause I thought you are aware of the Intel's Strategy to longer the life span of Sandy Bridge CPUs by using integrated heat spreader (which turns out to be not so good compared to aftermarket ones,hence low quality) instead of soldering cpu backplate with the CPU.

Whereas TDP is concerned, i7-4770K has 84watts TDP compared to 77watts TDP of the i7-3770K,although Haswell CPUs are supposed to power efficient.

Nope, never heard of it. My 3570k is @ 4.3 and never hits 50c.

what is your voltage at ? ivy tends to become a lot hotter once you start pushing the voltages up a little.the difffernce in the heatspreader on ivy and sandy is that on sandy they solder the die to the hetspreader and on ivy they just put some horrilbe thermal paste in betweeen.if you overclock higher maybe to 4.6-4.8 (i think) that is when the thermal paste starts limiting you.

I am not sure. I was lazy and left the motherboard settings to auto.
