Better CPU required?

Hi,

Recently built a small form factor system made up of the following

• ASRock Z97E-ITX/AC, Intel Z97, S 1150, DDR3, SATA III 6Gb/s, SATA RAID, PCIe 3.0 (x16), DP/DVI/HDMI, Mini ITX
• Intel Core i5 4590T, 1150, Haswell Refresh, Quad Core, 2.0GHz Base, 3.0GHz Turbo, 1150MHz GPU, 35W, CPU
• 16 gb DDR3
• Transcend 2242 256 GB SATA3 Solid State Drive (to go in the m.2 slot of motherboard)
• 250GB SAMSUNG 840 SSD as photoshop drive
• 1tb WD blue drive for everything else

Whole system runs great for 95% of the time, the only issue im having is when using Photoshop or Lightroom. It seems so much slower then my old full sized system which had a i5 3570K with a Nvidia 660 GPU. I knew the small form factor would be a compromise but was hoping for a little more when pushed.

Ive been looking at swapping hte CPU for either

i5 5675C

or

i7 4790T

Would either be worth it, ie will they give me the boost im after?. Ive looked on all the GPU comparisons and it seems gains are to be had, but real use feedback would be great.

Sorry for the lack of response , been away with work.

Yes photos hop and lightroom are on a sad in fact they have a whole ssd just for them, I've maxed the cache file they use and that has helped a bit but it still just feels slow when moving between images on light room, and when exporting batches of images.

The iris pro 6200 of the i5-5675C is the reason it's on my shortlist I knew losing the graphics card would have some impact, but not all that much as I had actually turned off the gpu support on light room as it never played nicely for me.

Heat sink is the Ince that came with my old i5 which is actually really good, cools well and is pretty near silent with this rig. Case also seems great at getting rid of what little heat there is due to the mesh top and I don't have the case stood tall on its side, so heat can disperse quicker.

Seems there is no straightforward choice between the 2 chips mentioned I was hoping you would all say get a specifix one.
