Hi,

Currently i own an imac 27" i5 3.2GHz, 24GB and a NVIDIA GeForce GTX 675MX 1024 MB. I'm fairly happy with it, especially the screen.
Im not a heavy gamer but i like to play Diablo 3 and Starcraft 2 a lot. I run them in native 2560 x 1440 resolution on low graphics. But the framerate is getting a tad low due all the updates from Blizzard, also just 1GB of GPU memmory isnt much. I dislike to play on a lower resolution due the fuzzier look. Buying a 5k iMac will put me in the same situation, running games on 5k resolution will require a GPU monster and the iMac will be very pricey.

First i was thinking of a Hackintosh system, but, i cant find a screen that is more less identical to the iMac (glossy etc) and all the hassle with patches, etc. so i decided to drop this idea.

My solution was to go for a second hand late 2013 model with an Intel Core i5 3.4GHz and NVIDIA GeForce GTX780M 4GB GDDR. This upgrade will cost me ~200 euro's after selling my current mac.
According to Notebookcheck the 780M is more less twice as fast as the 675MX. Not sure how reliable this is. http://www.notebookcheck.net/In-Review-Nvidia-GeForce-GTX-780M-GTX-770M-GTX-765M.93277.0.html


Would this be worth it? or is it still better to buy the entry level 5k iMac (m390) and play on (2560x1440) and is the fuzzie screen not a big deal at all on the 5K resolution iMacs?

If your problem is gaming my advice is: buy a 500$ gaming pc. way better for gaming way cheaper than upgrading an imac.

Bad timing for an imac upgrade in my opinion. The design is a few years old and macrumors advice on the buyers guide is don't buy.

I have a gaming pc, with an 300$ gpu upgrade every few years you can play everything on ultra 2k.

No mobile gpu imac can touch that
 
The iMac 5K doesn't look fuzzy at 1440p on most games. The exception is WOW. I'm not sure why but that game tends to be slightly fuzzy. However you can run it at 5K with a mix of low and medium settings at a decent frame rate. It isn't going to be a gaming machine but it also doesn't kick out the amount of heat a gaming machine does either.

If you can sell your iMac and get the 2013 model for $200 I say go for it.
