AMD 640 or Phenom 925

hey, i decided to upgrade to a 6850 and while playing bfbc2 i noticed that i did not receive a major boost as i expected in the fps over my old 4670, on average i see about a 5fps increase, so im assuming my current Athlon 5200+ 2.7ghz is bottlenecking it, so my first question is, is the 5200 supposed to bottleneck it? and also which cpu would be better amd 640 or the phenom 925, my motherboard is limited to those two processors being the best on the list since i cant find a 955 95w i heard the 945 should work but im worried and dont want to risk buying it and it not working. i could upgrade my mother board and get a x6 but im not looking to spend $300+ so will the 925 be a major increase over the 640 not only in game but in general use, i often convert hd videos and would like to cut down as much time as possible. the 640 at neweg is 99, while the 925 is 130
heres my motherboards cpu list:

anyone know if the athalon 640 will bottle neck the hd 6850? and how much faster can the 925 convert a file in general?

Firstly, yes, your CPU is causing a bottleneck. As for the Athlon vs the Phenom, try this link:

http://www.anandtech.com/bench/Product/122?vs=81

You could also use Tom's CPU graphs to compare them. They should be very close in performance, but the Phenom has a slight edge in gaming due to its L3 cache.

Here's the deal:

AMD Phenom II X2 545 Callisto 3.0GHz 80w: $66

or, if you feel like a Rockefeller: AMD Phenom II X3 740 Black Edition 95w: $69

CM Hyper 212+: $30 (before $15 rebate)

Here's the thinkin' ...

Your motherboard is going to hold you back a bit whatever you do, but it should be Big Fun. The PhII 545 is 80w which gives you a little OC volt headroom as opposed to a 95-125w CPU. You won't really be able to take advantage of the trip/quad higher wattage CPUs by OC'ing them to their max.

At 15x240MHz you will have 2 fast cores sharing that 6MB L3 --- that should be about right for your Radeon HD6850 --- fast dual cores still rule the roost in most gaming these days. I think the PhII 740BE can go here, too, but with more volts.

I don't want to get your hopes up (too much?) but I suspect with good cooling 14x280MHz is possible - I've been there easily with a GB 785g with a 550BE. A fan on the FETs (and/or the NB chip) will give you a little extra peace of mind :D  -- unlikely the 740BE will go here without those fans.

Then there is the unlocking lottery -- if you have a shot this mobo/cpu combo is the way to do it.

And most importantly, you need to be saving your money toward an AM3+ motherboard and DDR3 - have some fun with the GB740. With some luck (and $200 or so) by May you could be moving that PhII 545 / CM Hyper 212+ to a new Gigabyte 990GX AM3+ motherboard.

That would also be some Big Fun :lol:  and open up some great options for the future with 6850x2 and BD Zambezi.

also has anyone heard anything on the bulldozer i dont want to buy this cpu and then in a few months the benchmarks put the phenoms to shame. Also from an upgrade standpoint what type of fps boost will i receive im expecting ~15-20 depending on which proc i use, is that too much to ask? im currently getting around 30fps in BFBC2 at1400 x 900 resolution (max), and i used to hit around ~25 with my 4670

if xtremegear is a solid company, the 955 95w seems to be the best beating the 925 by 10-20fps in most games. but its also $177 which means that its not a great price/performance card when there x6 are faster, and similar in price, and im kinda thinking they made a mistake and its really 125 watt which i why i want to know how good the company is

Crysis WArhead
955 81
920 71
635 69

Fallout 3
955 86

because they didnt have stats for the 640 i chose 635, so my question is 1. would the 640 be on par w/ the 920? and 2. is the 955 price of $177 worth the extra cost?
comparably the 920 is $130
and the 640 is $99
considering that for games the 640 and 920 seem to be on par i would choose the 640(if they are similar) so $70 for on average less than 10fps doesnt seem like a good deal, but at the same time anandtech doesnt use max settings so i wonder if thats where the 955 would really shine

If that $70 extra is more than you can afford, the Athlon is unbeatable value.

well its not that i cant afford it, its just that i dont want to throw away money (otherwise id just buy an i7), especially because the difference in framerate changes per game, some are just poorly optimized, but like i said before if i were to increase the resolution would the difference in fps be more dramatic? or is that primarily gpu related. clearly the way i put it im more based on performance/ratio where the 955 is .46 fps per dollar, and the 940 is ~ .71 (using crysis fps assuming 940 is similay to 920) but i do have to factor in longevity which goes back to difference in frame rate, in L4D theres a 10-20 fps difference, in the other 3 games, its only single digit numbers

now that im looking at it, it all comes down to 1 question which is kind of hard to say, so ill lengthen it,:

im trying to get my 6850 to its full potential, obviously the 955 is stronger, but after this upgrade, for my next one i will have to buy a cpu/ motherboard, (i obvioulsy wouldn't buy another motherboard and keep using my cpu)
so basically would i see a large fps increase in 2 years (keeping my gpu, but upgrading cpu/mobo), or would i find my gpu bottle necking my cpu, because (if i explained this properly) if my gpu will bottle neck the future cpu i might as well buy the 640 since both the 640 and phenom would be obsolete.

ps, yha i understand the 955 will be less obsolete, but i would be getting low fps forcing me to upgrade my gpu, so i have to consider if i upgrade my gpu to the future 8xxx or 9xxx series my 955 would probably bottle neck my gcard forcing me to upgrade the mobo/cpu anyway. so it comes down to that avg difference, since i cant just upgrade my cpu only. again im not sure if im thinking logically, but thats why im here dont hold it agianst me

just because im not so sure how clear that is and i just thought of this, simply put is the 640/955 utilizing my gcard to nearly 100% (obvioulsy the 955 is doing it more than the 640) to where upgrading to the future i10/11 or what every they call it, would i be a waste because i would have to upgrade my gcard to see a good fps increase?

You are talking to yourself again :o 



You ... should ... have ... listened ... to ... me ....

The PhII 545 is now $76, the x3 740BE sold out, and the CM Hyper 212 is $38

NO!

An AM3 processor, either a 95w Phenom or Athlon, will run on your AM2+ motherboard, and will move to an AM3+ motherboard (for which you will have to purchase DDR3).

Your HD6850 will not be 'left behind' in the foreseeable future. As a matter of fact, it will look rather sporty sitting beside his twin brother in an AM3+ 990GX with a PhII 740BE.

well the x3 740 isnt on the list, and the problem for me is that although i game, i also use it for slight video editing, which is where the 4cores will win if im converting files.
but as for the cpu chart, how reliable is it? by looking at it, it skips alot of procs which it should be able to use, especially for am3/am3+ is seems as long as its 95 watt it should work, but i dont know for sure which is why im here, and im not a big on overclocking, because im not good at it.

Bulldozer will most likely be a new socket design (AM3+ or somesuch) but to my knowledge no official specifications have been released.
