would an i5-750 at 3.8ghz bottleneck a 7970?

i have -
gigabyte p55a-ud3
8gb corsair vengeance lp ddr3
ocz vertex 2 64gb
corsair 650watt psu 80%

looking at upgrading from a 5850 ocd
 
I guess this would depend on the game, but overall i'd say no. And even if it did slightly bottleneck, just crank up the AA for no loss of performance. An i5-750 at 3.8Ghz is still an excellent CPU.
 
i have the same mobo and chipset at 3.6 on stock getting a gelid tommorow so hopefully can push it closer to your 3.9 since it was stable at 3.8 but running a bit too hot for my liking but again its under stock so hardly surprising to be fair. also i doubt very much you will bottleneck with your overclock, but to be fair if you aint gaming above 1080p then the 7970 is a bit overkill atm a 6970 is £160 cheaper and you could throw in a i5 2500k at that difference.
 
I got the gelid tranquillo the other day. With all my case fans set to 15% in the bios, the temps peak at about 76c in prime. This is @ 3.9 with about 1.29v set in the bios.
 
Mines running nicely at 3.6 with power savings all on. Always wanted to get to 4ghz but the effort involved seemed like too much for little gain :P
 
ok settings are as follows -

cpu clock ratio - 19x
advanced cpu core features - intel turbo boost tech. - disabled
- cpu cores enables - all
- cpu enhanced halt (c1e) - disabled
- c3/c6 state support - disabled
- cpu thermal monitor - disabled
- cpu eist function - disabled
- bi-directional prochot - auto
Qpi clock ratio - auto
Qpi link speed - 6.4ghz
Uncore clock ratio - 16x
Uncore Frequency - 3200mhz
Base clock(bclk) control - enabled
BCLK frequency(mhz) - 200
Extreme memory profile(x.m.p) - disabled
System memory multiplier (spd) - 8.0
memory frequency(mhz) 1333 - 1600
Pci express frequency(mhz) - auto
cpu core drive - 800mv
pci express clock drive - 900mv
Cpu clock skew - 0ps


Cpu Vcore 1.15625v - auto
Qpi/vtt voltage 1.100v - 1.230v
all other in advanced voltage settings are auto.


Hope this helps and wish i could push some more out of this cpu really.

PS. Liverpool won 1 - 0 :)

temps idle around 41 and 73 on loads using prime95
