i Have core 2 duo e6750 @ 2.66GHz
6gigs ddr2 ram ______ _____
Stock HP PSU wit 365w 12v-------- 12a 12v (CPU) ------- 14.5 a

And will buy HD 7750 to play bf3 online medium to high 1280 x 1024 or 720p on low to medium to high settings so will i get about ~40 FPS?

And HD 7750 cant reach its full capacity due pcie x16 1.0 or pcie x 16 has enough bandwidth rate for hd 7750?

will it bottleneck
will also play black ops 2 720p low-medium

I have the E8300, a little more powerful then the E6750 set up with a 7750. On 64 player servers, bf3, cpu is pretty much flat out 100% and 7750 is at like 60-70% @ low preset 1680 x 1050 25 fps.

so yes your cpu will bottleneck the card in bf3 multiplayer but it should be fine for non-cpu intensive games :)

The card is being used with with a GAG41M-COMBO which has pci-e gen 1.1, no problems
 
you will likely not get any higher fps due to cpu bottleneck

I run a 5650m and a pehnom IIx4 2ghz in CSS and in 64 man servers, my cpu gets maxed but my GPU load is only 15% for high settings and 4xMSAA 16xAF 768p

If you're not being bottle necked, expect performance up to maybe 50% higher (maybe even more) than these ones since this is with old drivers and at a higher resolution than you and ultra settings

Ashish65 my cpu is about same as yours so can u see ur FPS on these settings low on 1280x1024 64 player map
i mean i just want 40+ fps cuz 720p low(only multiplayer) is also a good graphic and will buy core 2 quad after 3-4 months
 
See at 1368*768 at high settings(vsync and AA to off) i get 40 fps in multiplayer so your resolution is slight bigger than me so assume -4 fps and your core 2 duo is old cpu and it not same as me as they are different architecture so -10fps so you will get around 25fps at high.
 
In multiplayer BF3 it really won't matter what settings you are running at you should get about the same FPS either way... Due to your CPU bottlenecking your fps to something like 20-25 FPS... It won't be so bad with less people on the map - so you might have to just stick to smaller games to have it playable.'

Edit: Or upgrade your CPU.
 


there will be no bottleneck hd 7750 in pci 1.0

see here - even high end gpu loses 5% performance loss.no measurable difference @ pci x16 :D

playable means 30-40?
And dude after researching i saw that
Intel Pentium D 2.8Ghz ( which i had but sold to get the core 2 duo silly me )
is better than core 2 duo in gaming.
is that right..
i sold whole CPU 40$ and boought core 2 duo dc 7800 hd for 300$

u have been helpfull the most bro really but to tell my by installing windows 8 from xp my moniter could display 1080p graphics ow yea
so 1080p low preset hd 7750 online will be playable? cuz less bottleneck as more will be on gpu right

also bro
1280x1024 has more pixels than 1368x768
large amount so u get 40 fps online on high i will get 30 on high cuz of cpu

and that of changing my montitor ressoultion to 1080p was a bug and viewsonic told it might damage hardware cuz i bug with hv frequency over range ( loled when i got 1080p on 2005 model moniter 17" )
