The 980ti is FAR from being a downgrade from 2x 290x cards. Plus way more Vram, and way better drivers. Now you can use all the Nvidia only features in games as well. Oh, not to mention how much cooler it runs too. Yeah, downgrade LOL.
I love my TX and wouldn't give it up for anything AMD has to offer that's for dame sure
You'll be way happier with that 980ti, and running 1 card will play so much smoother. Not sure what the Power Limit Max is on the G1, but I can mod your stock bios, ONLY to raise the Power Limit up to 120%, but not change anything else for you if you like. That will let you boost at 1500mhz with no throttling and still have all the features still work as in throttling down once it hits the temp you set it too. I modded my 780ti's and my TX bios for 120% Power Limit and it's great. I run my TX at 1450mhz all day long, but I'm also on water and my card is usually at 32-40c while gaming.
If you want me to mod your stock bios for you, just let me know bud
Also, I help a lot of people out on overclocking their cpu to get the most out of it safely. I run my 4790K at 5ghz 24/7 .. I have bios pics of my settings in my build log on page 3 I think if you want to take a look. I'm sure yours would need a little tweaking from the settings I use, but we could get you up past 4.6ghz for sure.Edited by Hambone07si - 7/3/15 at 6:16am
