you can see what my system is but all that heat inside case makes me worry about buying these cards. Would the ref 7950 heat up the case any less? thanks for your input.

 reference cards will heat up the case less because they use a blow style fan that blows all the hot air outside of the case where as a custom cooler will blow all the hot air inside the case. My 7970 is reference and the heat from the back of my case is crazy but insdie my case its nice n cool. 

 

I cant tell you what kind of temps you should get from the current cards you listed as I dont own them so my experience is null n void with those

Hm that doesnt happen to my GPU using 12.8 drivers. There are no issues and Everything runs smoothly for me.

Here is the link for anyone who wants to try the 12.7 Modded drivers. IMO they work fantastic

http://benchmark3d.com/amd-catalyst-8-981-2-12-7-beta-7900-mod

Also I setup a custom Fan profile using Trixx and man the fan on this thing gets loud. I did a MAX fan speed of 50% and I can easily tell the difference from 45% to 50%. 45% is semi inaudible where are 50% is kind of annoyingly loud in a way. I played BF3 for a bit it never broke 65c VRMs stayed nice n cool at around 48c

This is still at stock sorry but i will get to the OCing soon. Stock clocks on my 7970 are 925/1375

Is there a reason to install the modded driver for the highest level card? I thought the purpose of the mod was to unlock features on older / lower ranked cards that are only available to the 7900 series (but you already have a 7970).

Too many lol. He was really selling the 660ti too. Sorry to xfx owners, but my card could wipe that xfx card up easily. The DC2 670 performed exactly like mine did.

hey guys, i have 2 questions:

1) should i replace the thermal paste on my Sapphire 950Mhz Edition card?
2) What other 7950 have non-ref pcb/ref 7970 pcb ? (considering CF in the future if the price drops in my country, and the 950Mhz card doesn't look like it will drop its price any-time soon)

thanks for the help!

So, I dropped down to a single screen over DVI, when I booted up the temp was in the mid-low 40s C this time. I loaded up my game and no problems, even played for about a half an hour and noticed nothing.


I did notice something else. When I had the two screens hooked up, it always idled at 500MHz for core, and higher for Memory.

This time, it idled at 300MHz and 150MHz memory, which seems more in line with the research I've done.

Wondering what I'll need to do to add in the other two screens for Eyefinity and keep this stability?

What kind of performance can I expect with Crossfire 7950's @ 5760x1080 in current games like BF3?

I'm looking at the Sapphire Flex because I want to eventually run with 4 monitors. 3 in eyefinity +1 extended.

A single 7950 will do 3240+ x 1920 very well, but tends to lag a bit when done in 5760+ x 1080. Crossfire will blow any game out of the water right now unless you're heavily into modding texture packs.

for now i still use my 2-3 year old samsung 1080p screen (P2370 non-HD) but its hopefully just for now. i'll more likely to get a 1600p screen in a few months, and i don't have the space for 3 monitors on my desk. i was just considering even though i know it is possibly a big overkill and better wait ti 8xxx series if i wish to spend money on a new GPU.

what about the thermal paste question, would my warranty be void if i'll replace it?

i think your comment pretty much sums up if i need CF (and i don't)

Havn't owned an ATI card since 1xxx series and i'm already experiencing so many issues I never had with nvidia.

Doom 3 white screening, metro 2033 freezes and gives error, multiple games underscanning etc. Stuff used to simply work. But in a way I like it and ill just look at it the way I always do technology. The more messed up and problematic it is and the more effort it takes to fix the more i'll learn smile.gif
