How bad will a Phenom II X55 bottleneck an Nvidia 680?

post #1 of 37
Thread Starter 
Hey quick question. I'm running a 3 year old system that I built... and to be honest it handles all the games on HIGH @ 1080p at very acceptable frames, I havent really had a need to uprgrade, but now I want to upgrade my monitor to a 27" IPS @ 2560x1440 and I know I will have to upgrade my videocard if I plan to game at that resolution.

My question is regarding my CPU, Im wondering if a Phenom II (955 BE @ stock clocks) will bottleneck an Nvidia 680, if so, by how much? and most games being port-overs and not very CPU intensive, will I even feel a bottleneck?

The system specs:

AMD PII 955 BE stock clocks
Asus M479XTD EVO Deluxe
ATI (Gigabyte) 5850
4 GB G.skill
Antec 550W TruePower Modular

Thanks any savvy input would be greatly appreciated.

Best Regards,

OC the CPU to 3.8-4ghz while having a proper fan like H212+ or H60

A lot of games these days are pretty cpu intensive. You could try and overclock it to around 4ghz, but you will still have a bit of a bottleneck, particularly at that resolution.

I forgot to list my fan, its Tuniq tower 120 extreme, I got it because I planned to OC all along but I never really got around to do it...especially since Ive been able to play just about anything on high at very acceptable frames, so I never felt like it was something i really needed to do.

do you think Ill be able to game at 1440p with an OCed X55 and a 680 and get playable frames?

I'd get an i5 2.5k but that would pretty much be a whole new build... and with the 680 plus the monitor I want.. it'll over stretch me quite a bit.My goal is to get away with gaming with a 680 and an x55 for at least one more year, and then do a whole new build.

You will get playable frame rates.

It is hard to say, because it really depends on what games you'll be playing. Certain titles really choke the Phenom II architecture. Do take a look here: http://www.anandtech.com/show/3877/asrock-890fx-deluxe-full-review-and-an-investigation-of-thuban-performance-scaling/7
Overclocking the memory controller (CPU-NB) can help alleviate bottlenecking and allows Phenom II to have a very scalable overclock, but to get its full potential you must have high speed ram. Although, with Deneb getting past 1600 RAM speed can be a challenge.

Well, that is THE question, what games? I hate to say it but the title selection is very limited nowadays. THese days Im playing BF3 and Skyrim... Ill be playing diablo 3 and dota 2. And whatever games are coming out in the near future I guess... Mechwarrior Online and planetside 2, who knows. I dont think any of these games will be paradigm shifters in terms of system requirements. And given that the Ps4 will be out in 2013... itll probably be a about 2 years before we see the next-gen pc games.

See, if there was a ton of next-gen pc games in the market, Id probably just do a whole build, but it snot really worth it, I mean I play BF3 on High @ 1080p with a single 5850 jus tfine, no lag whatsoever. And I know that 1440p is a whole different animal, but still, somehow Im confident that a "bottleneck" on paper wont be as bad in real performance.

Yeah well, BF3 is much more intensive on GPU, which is not to say it isn't on the CPU, just not nearly to the same degree. I say overclock it and buy a 680. I believe you will be bottlenecked in skyrim though.http://www.tomshardware.com/reviews/skyrim-performance-benchmark,3074-9.html Nothing worth spending money over though.

The only game you will noticeable bottlenecks in are games that favor Intel CPUS anyway such as Skyrim and Star Craft 2.

Either way, bottleneck or not, you'll get a nice performance boost.

2560x1440? Not much bottlenecking to worry about, you'll be fine.
