RX360 could definitely do it. The RS360 would also probably handle both.
When you do get around to watercooling feel free to post up or PM me
(your rig's title is outdated I believe. I think someone posted that they flashed a 7970 BIOS and it didn't do anything)
I sure will, but as for now, i'd rather get a second 7950, as i've explained before
i've read a thread (not on ocn) about flashing the bios and it seems like a half unlock. i'm now pulling numbers out of my bottom but the results were as follows:
7950 @900mhz score: 1
7950 @900mhz w/7970 bios score: 1.5
7970 @900mhz score: 2
maybe its because the voltage is higher or the memory is clocked higher with the 7970 bios bit it seemed to be right in the middle of the two.
I beleive this was the post. Sorry I don't know how quoting an article works, but here goes:
" Right some odd Heaven results here:-
7950 @ 925MHz / 5500MHz = 1504 points
7950 on 7970 BIOS @ 925MHz / 5500MHz = 1545 points
7970 @ Stock (925/5500) = 1584 points
So even though according to GPU-Z the shaders are not unlocking, flashing to the Asus 7970 BIOS is definitely giving a performance boost, though its not quite at genuine 7970 performance levels, kind of like half way from the results.
So either some shaders are unlocking or the 7970 BIOS is making other improvements, maybe memory timings etc. which is giving the boost.
Still flashing the BIOS is so easy anyway and it would appear the 7970 BIOS is giving some performance enhancement even when clock speeds are identical.
