Black Ice GTX Xtreme 480 Radiator(2 pieces)

Swiftech MCP655™ 12v Water Pump w/ Speed Control and 3/8" Conversion Kit (317 GPH)

Distilled water

IandH Silver KillCoils - Antimicrobial .999 Fine Silver Tubing / Reservoir Strip

Gelid Solutions GC-3 Extreme Thermal Compound - 3.5 Grams (TC-GC-03-A)(2 pieces)

 

I have two options;use the 295x2s in CF with  no loop.The other is getting the 780 Tis in SLI.Question is will the 295x2s be THAT much better than the watercooled 780 Tis?I really like watercooling so would not mind a little difference in performance.Again,will the difference in performance become minimal when the 780 Tis are overclocked with such a beastly loop?

As far a graphics performance is concerned you should choose the cards based on the games you play, I just took a couple similar setups through some games  here. http://www.overclock...color_r9_295x2/


Processor Intel Core I7 920 @ 3.6
Memory Mushkin 998995 Blackline 12GB 9-9-9-24
Motherboard MSI X58 Big Bang
Graphics ASUS GTX 580
Power Corsair AX 1200,
Monitor Gateway UXD3000, LG W3000H, ASUS VG236 x 3

The 780TI has one big flaw for long term 4K support, only 3GB of video memory.  With 3GB being used at 1440p in some games now I would rather have the 4GB AMD is offering unless you opt for one of the 6GB 780TIs instead (this is assuming they have made it to market, I haven't been looking but evga had been working on one)

 

PERSONALLY, I would go for option #3 2 x 290X cards and watercool those. Then you have OC headroom and cooling the 120mm rad of the 295x2 can't match, 4GB of video ram and less money spent. 

 

As a side note I don't see any reason to watercool your motherboard, modern chipsets run cool and the VRMs need minimal airflow to keep cool with the stock setup. It just introduces more restriction to the loop even if it does look cool. I'm far enough removed from custom watercooling these days to give much more opinions on that front.  Last custom loop I bothered with was back in the days of the early Core 2 Quads.  Still got most of the parts too :)
