That's about the price you are going to get for anything of any quality.
I own both sets of cables.
EVGA cables are sleeved in a stiff braided nylon, or that is what it feels like to me. Very smooth to the touch and despite being stiffer than cablemod it cooperates with how you want it to lay.
The cablemod cables I have for my Seasonic, are sleeved in a 550 cord type fabric, more flexible, but depedning on how long the run is, may not cooperate very well staying bundled. Advise getting cable combs.
 
I like that I got four 8 Pin VGA cables from EVGA compared to CableMods three. So I had to go with two of the three 8/8 Pigtail versions which in my eyes is not as good looking.
Off the top of my head when it comes to the VGA cables, EVGA gives you four 8 Pin VGA and two 8/6 Pin VGA cables. CableMod gives you three of each, which is dumb if you ask me. Why an odd number? Should be like EVGA's.
So if I were you based on this, I know it mainly applies to those who SLI, I would go with EVGA cables. Otherwise, meh, they both look good, and do the job well.

Hey @loveha , that was an informative post!

Question:
Is that the ModMesh. or the ModFlex cable material?
 
Comment:
Cable combs make the cables more organized and uniform which makes them look much better (IMHO).

I hear ya, but CableMod allows you to configure any number of custom cables.
Were I was choosing CableMod, I think I'd go the custom route. I'd order one 24-pin, one 8-pin EPS, one 4-pin EPS and however many PCIe 6-pin or 8-pin cables I needed (depending on how many GPU's I would be running). This way, I could choose to go with full cables or just extensions (or a combination of the two), choose the exact length I wanted for each cable and even choose the color of each stand of each cable.
I don't think I'd bother with the other PSU cables unless my case didn't have a PSU shroud.

i have to say i feel i NEED to get coloured cables soon, its such a nice look, i just wish psu's could start coming with a choice of cable colour so you dont need to buy a second set, i mean come on evga, would it kill you to offer your psu's with a choice of cable colours at a discount over buying the psu and the cables separately ?

I know, right?  I'm going to have to spend almost as much on a set of cables as I did for the entire PSU/cables... it kind of sucks, but the white looks so good.  I'm kind of considering trying to sleeve my own cables.  I like that kind of monotonous zone out activity.

You know,I've never actually looked into how much I'd save doing it myself, then again, it probably wouldn't turn out as clean and i can be very lazy lol

It probably costs a little bit the first time you do it because you'd have to buy a few tools and such that you wouldn't need to buy again.  If you do it somewhat often, I imagine the cost is less than half that of buying them.  First time, I'm not so sure though.

The white set i purchased from evga for my 750W P2 power supply. the cable with 4 pin power connector on it was a bit short. If i was using a full tower case, i wouldn't of been able to use it to power my fan controller.
 
The PCI-E cables were extra long compared to the accessory 4-pin cable.
