Will my CPU Bottleneck HD5770?

post #1 of 16
Thread Starter 
Hi guys.Recently I was thinking of getting a new graphics card,as my old 9400gt can barely play old games.I was looking at the HD5770.But will my CPU bottleneck the card?I'm also thinking of adding 2gigs of ram.Will it be enough to play dirt 3 or crisis 2 at 1366x768 or do i need to upgrade my CPU as well?

Yes it will.stock clock @ 2.2 ghz is quite low for today's games. However you should be able to overclock that processor up to 3 + ghz and dang you are fine now. i managed to play crysis 1 and dirt 2 on that resolution as well using 5770 hence I would say it is doable.

I got a HD5770 on a P965 Mobo with a E6420 C2D at @2.8GHz and it's good for light gaming really.

My kid is playing BFBC2, Sims3, L4D2 and stuff like that, no stutter at 1280 X 1024...

so yes, overclock that CPU o yours...you should reap some benefits...

With stock cooler you can take it to 2.8Ghz easy .Watch your temps to be around 70-75C on full load and dont go any higher than 80C. With a 2.8ghz OC you wont have bottleneck with your 5770 especially on 1366x768 resu.

Take a look here if you need help with OC

Yeah.Actually I'm new to OC.My board doesn't support bios overclocking.I used setfsb to OC my CPU.With stock cooler i got up to 2.7 GHz.Temp maxed out at 60C under full load.Performance was OK with no hangs or crashes,but i got a little worried about the temp so i didn't push it further.Can i really push it up to 70C?And since my board is not a overclocking enable board (Though it's quite stable) will it cause any problem?

60C is not alot for Intle cpu's, I think duo's are safe till high 90s.

No it wont cause any problem . 60C on full load is very good everything under 70C its good. After you finish your overlock (no need to go more than 2.8 Ghz) run some benchmarks just to be sure about stability such as Cinebench 11.5,prime95

90's is bad, don't go over 70C

5770 will be bottlenecked at that resolution but you could enjoy some AA for a low cost. IF you get that CPU to 3 Ghz then it won't be a problem, a small bottleneck won't kill you.

Nah I just wanted to say that duo cores can survive high 90s.
My own temp limit is 60C tough ;>.
