X51 R2 CPU possible bottleneck/ CPU upgrade

Hello all,

I have these following 3 questions regarding my CPU and a possible upgrade I'm thinking, but firstly I would like your opinion if an upgrade would be really worth it.

So my build is the following:

X51 R2

WINDOWS 10/ x64
BIOS A10 (up to date)


i5 4460 3.2 ghz / max turbo 3.4 ghz

GTX 1060 6GB (EVGA mini - upgraded from GTX 745)

SSD Corsair 480GB (upgraded from a 2TB HDD which is removed from the machine).

330W Power Brick (upgrade from the 240W).
DVD Rom also removed.

Overall my X51 boots like in 5 seconds and performs very well.

However, I would like your opinion on the following:

1. Do you think that my the i5 4460 3.2 ghz bottlenecks the GTX 1060 6GB? , and

2. Do you think that upgrading to an X51 R2 compatible i7 would make a difference on gaming or not really ? - would it be worth it? On which case a compatible i7 would make a difference anyway?

3. Which i7 is compatible with my machine R2 BIOS A10 ?

Thnk u :) !!
your i5 shouldn't bottleneck the system at all I think you are fine.the difference of i5 and i7 for gaming is small,you'd notice the difference if your running multiple games at once tho but that's about it
Thnx for the reply! noted.

I asked this having also in mind a possible gpu upgrade in the future.
Do you think that the i5 4460 3.2 ghz can handle even a gtx 1080 ?

Which gpu would you reccomend as the higher cap limit for this cpu?

Thnx again
