780 Classified Hydro Copper or 780 Vanilla + EK block?

post #1 of 3
Thread Starter 
I recently added water cooling to my setup and now its time to retire the 570 in my rig for a new GPU. I know I'm definitely going with an EVGA 780 but I don't know which one and could use some advice. I'm either going to get the 780 Classified Hydro Copper or a vanilla 780 and an EK waterblock.

I've heard that the Classy's are cherry-picked and have more power phases to handle better overclocking but the Swiftech block isn't that great and the cards really isn't meant for anything but subzero cooling. On the other hand, I've heard most aftermarket waterblocks will perform better but the vanilla card won't handle the higher voltages as well.

Since Classy's don't usually have compatible aftermarket waterblocks, I'm in a dilemma. Which would you guys go with and why? Is any of the information I have heard wrong?

My first pc build, I wanted to do a custom water loop, and decided to go with hydrocopper 580's sli'd. I thought it would be easier for me since it was my first PC build, and I was a little nervous of doing a custom loop at the same time. Looking back... I remember I couldn't really test the cards out until I filled my loop and leak tested a day later. I had to modify my case to fit all my rads... so it took a while for me to set up my loop to even test my cards. I'm sure everything will work fine for you... but it would have sucked if one of the cards were DOA. Another thing I had to think of was that swiftech GPU water blocks, which are used on the hydrocopper cards, are pretty restrictive. To make sure I had decent flow rates in my loop, I looked for a CPU water block and additional blocks that had high flow. Running the hydrocopper blocks in parallel helped increase flow rates.

I'm in the process of updating my rig, and I was set on just going air cooled on the GPU's because water cooling is expensive. I made sure I got cards that I can buy water blocks for...if I wanted to water cool in the future. However, I was lurking in the water cooling forum, and wermad's build thread gave me the bug to water cool my GPU's. I'm updating my rig with 3x GTX 780's... I thought I would need higher flow rates with 3 cards, and go in series this time, so I decided to buy EK blocks + back covers. Without the back covers, it came out cheaper than the regular EVGA HC GTX 780's. When I receive my 780's I'll be testing/using them with the stock blower fan on my current rig. I mainly bought these cards for my 4930k RIVE update build in a few months. It will be nice to test all my new components with air before installing it into my rig. After everything tests okay, then I will install the water blocks and install them in my rig. One other thing I was thinking... it might be easier to sell in the future if I put the fans back on, and sell the blocks separately... maybe.

Well I'm not too worried about flow restriction. I have dual pumps with only a 360 rad and CPU block to worry about. They should be able to handle adding a GPU into the mix. The only things I'm worried about are how high of overclocks, how stable long-term they are, and what kind of temps will I get. No point in overclocking the card if its gonna burn out after only a year or two.
