e8400 @ 3.8ghz, best graphics card to get that wont be bottlenecked?

post #1 of 9
Thread Starter 
Im looking to get a new graphics card at $200 give or take, maybe more, but I cant upgrade my motherboard or cpu just yet, nor do i know when thats going to happen. My processor is pretty old tho and was wondering whats the best card I could get that wont be bottlenecked by the CPU, i was thinking a 560ti or 6870 maybe. I was looking at the 560ti 448 core cards which are around $300 and can be overclocked to be close to a 580, but I feel like my CPU would greatly bottleneck the card at the point.

So whats the best card an 8400 can take without bottlenecking?

Yes, you are more or less right. The HD 6870 or the GTX 560 (non ti) will be the best choices for your CPU. The GTX 560 ti will already be bottlenecked by your CPU, let alone the 448 core version. Remember that Nvidia cards in general need a faster CPU to produce the same framerates, athough Nvidia apparently adressed that problem when people have Dual Cores in one of the newer driver releases. I don't know if it actually helps because I haven't seen anybody test that claim.

You can try overclocking the CPU to 4 Ghz and get the 560ti id you are thinking about a future system, but the card will be bottlenecked by the CPU in newer games.

I would go for a 6870, though really a e8400 shouldn't bottleneck a 6970 on a game only using 2 cores. Overclock it to 4.5ghz and have some fun biggrin.gif. Though really up your fsb to 480 and set your voltage to 1.3 (so cpu-z reads 1.3v will need to be higher in the bios. I would enable load line and disable all the power saving settings. Also dont let your ram get to much mhz, you should be able to cap it around 980mhz(490mhz) or something. also up your NB voltage to 1.3v as well.

I have a ud3p ep45 board with a q9550 and can easly do 480fsb at 1.28v and can do 4.25 (500fsb) at around 1.38v. You chip should be no different if its E0

thanks for the replies, im pretty sure i can reach atleast 4 ghz on my crappy artic cooling freezer 7 if i up the voltage, its at 1.25v or so i think. I have another question about 1gb vs 2gb vram with my particular setup. I play at 1920x1080, and i know for MOST games it wont do anything, but I like to play skyrim and Im adding lots of mods, which i hear will easily go over that 1gb vram. I can get a 560 non ti or 6870 with 2gb ram for about $230.

I would go for the more V-Ram, newer games are stating to become memory hogs. Card will serve you better in the future.

If you can go for more VRAM, please do, it's a wise investment in the future.

As to overclocking your CPU beyond 4 Ghz, be careful, your board is not a P45-UD3P that DzillaXx mentioned. That board has more VRMs and they have heatsinks. Ensure that you have good airflow in your case and consider getting some heatsinks if you intend to go over 4 Ghz.

Your 8400 is still a very good chip. I have fond memories of it. Have a crack at 4 Ghz, it worth a try.

GTX 560 / 6870 should see you through. thumb.gif

thanks everyone for the input, Im most likely going to buy the evga superclocked 560 2gb ram card, just gotta wait a couple days for my next paycheck lol =]

anything past a 275 would be a bottleneck technically, get a gtx 460... very affordable and in the right power range
