Hello,

I am planning to buy HD 5970, will this bottleneck my system?
@ stock 3.0 and @ OC 3.6GHZ? You can see my system details in my profile.

If not, does anyone have an idea how it will perform?
Also what will be the difference with i7 920 and PH II 945 with this video card?

Thanks

945 are a bit more fussy on overclocking than its 940 counterpart. 3.6 might be a wall for you. I've seen it go as high as 3.8 on air

i7 will perform considerably better in games than the 945. Heres a comparions between the 920 and then PII 940

In none of those tests do a see an I7 price/upgrade justified...you net what 20 fps at best?

I doubt this guy is buying a 5970 to run without AA/AF

A 5970 @ 1080 will have no problem with any quad past 3GHz. You'll be fine and so should your PSU.

Just throwing it out there; 20fps is quite a jump.

He never said he was going to upgrade. He just wanted to know how much better a i7 is to a 945

not a psu issue. My 945 hit 3.6Ghz easy, and took me a while to land 3.75Ghz completely stable with a great deal of tweaking. The 945 is not the best overclocker by any means, that said with 3.6Ghz i doubt there will be a big bottleneck, perhaps a few fps. I would say you are fine, but if you can overclock it higher then it wouldn't hurt

D3TH.GRUNT, can you please share the values? core voltage ? ram ? etc... ? details please, cuz I would love to reach 3.75.

Thank you!

I was simply pointing out that the "considerably better" performance increase on the I7 is far from meaningful in gaming

Yeeeeaaa...did you look at the benchmarks?

The I7 had 90FPS in a benchmark whilst the AMD held 70FPS...20FPS right there isn't going to make a XXX$ investment difference...with AA+AF up the AMD rig easily catch's up to the I7 rig

Why they where testing the CPU's out with the I7 clocked higher is beyond me

I don't like the looks of that PSU.

A brand I've never heard of and four 18A 12v rails :/

It necessarily isn't bad, but I think one big fat rail is better.

Hes only saying that because he just recently switched to a 920 lol

Yea 20 FPS is a huge gain! But, your point makes no sense based on your comparison!

1st of all if your going to compare Intel and AMD CPUs do it from a cost standpoint! When you start there your going to match the cheaper 965 against the i7 920! See where those benchmark results get you! Prob not a 20fps difference!!!

In case you needed help with that comparison

I don't think he was comparing the systems as much as just mentioning that 20FPS was a big jump...which its really not when the systems are already in excess of 60FPS+

This I agree. That PSU is probably the issue.

Single rail or multi rail doesn't matter. Its just as long as the there are enough amperage on the 12v rail to power up your main components (CPU, Video cards, etc).

My brother bought GTX 285 Point of View I think 1GB DDR3 anyway I did benchmark with Vantage on my rig with his video card, and there is something I do not understand.

I know that his GPU will score lot better than mine HD 4850 1GB DDR3, but why is the CPU Score difference so extreme BIG ??

Please take a look at the screens:

My rig - XFX HD 4850 1GB DDR3 - CPU OC @ 3.8



Settings



My rig - POV GTX 285 1GB DDR3 - CPU OC @ 3.6



Settings



29k difference?

The human eye sees a maximum of around 60 frames per second, 90 - 110FPS is moot.

The 965 beat the i7 in GTA IV.

From what I've seen, Intel processors are number crunchers, while AMD CPUs favor gaming.
