7870 for a E8400?

This topic is locked from further discussion.

#1 Posted by Goodfella_no4 (348 posts) -

My 8800GT finally bit the dust. It happened before and I baked it and it came back, now I baked it again and some capacitators fell off. RIP, it served me well, and I was on borrowed time since the first failure. So, no complaints.

I am thinking of getting a 7870 or a 7850 to power my system (C2D E8400 @ 3.6 GHZ, 4 GB DDR2-800 RAM, P35 chipset with PCI-e 1.1).

I don't want to upgrade anything else. I have a 19" 1440x900 monitor, that I may upgrade down the line too. And sometime I play on a 42" 1080p TV.

What do you think?

the 7850 is a heck of a card. enjoy

but on a more realistic note a lesser card like an hd 6870 is leaps and bounds over your 8800gt

it will be ok. A decent dual core at 3,6 is still ok for either 7850/70 ( though at 1440x900 with a 7870 you will see some cpu bottleneck from cpu intensive games so probably a 7850 would be a better pair to your cpu )

The CPU bottleneck will be there regardless of the resolution

True.. but it would be overshadowed by a GPU bottleneck at higher resolutions/levels of AA, etc..

Ahh, I see.

Thanks guys. The price difference is not that large between either. When you talk about bottlenecks, how much would that "practically" be? Considering that all the reviews I read were on a lot better CPUs that the one I have. Also, would I see any difference due to the fact that my motherboard is PCIe 16x 1.1. I am looking forward to play Deus Ex, Skyrim, Battlefield 3, Serious Sam 3, Hard Reset, etc...

it doesnt really matter if its PCIe 1.1 or 2.0 Depending on the game . Now days most games are gpu dependent and you will see no bottleneckes or very small bottleneck in most games The only time you will see some noticeable bottleneck are games that take advantage of 4core cpu's

I previously had an E8400 @ 3.6 ghz using an Nvidia 8800GT so I know exactly what you are currently running.

I had upgrade my GPU from the 8800GT to an AMD 5870 (when the 6950's came out and I got it for like $175.00 on sale). At the time I was playing Rift so it's the only game I can really give you information on. Needless to say I saw a very minimal FSP increase in that game even though I really increased my GPU power.

I then changed from the E8400 for the I7 2600k and I jumped about 30 FPS. So I can't say for sure you will bottleneck in all games but the CPU will definitely hold you back in certain games for sure.

The thing is that I have recently bought a PS3 and now with this "compulsory" upgrade, I won't have the money for an overall upgrade (CPU, mobo, RAM, PSU and GPU). While I want future-proofing, I don't want to over do... Because I know it will be a big while before I do a total overhaul, so my new shiny GPU may need replacement then. But I don't want to get something out of the bottom of the barrel.

I also jumped from E8400 and frame jump was massive. 30+ as you said. That was with a GTX 460.

since your resolution is low, you have a dual core cpu and you've been used to a 8800gt then there is no point in getting a 7870. That graphics card is in most cases equivalent to a 580gtx which really wouldn't be right to stick in your computer. I highly recommend a 6870, you can find it for about $150 and you will definitely be happy. Its about 3 times faster than you're old 8800gt as well.

Thanks a lot for all the replies.

I finally manned up and bought a Sapphire 7850 OC edition. WOW! Great card for the price, EGP 1550 which roughly equals USD 255.

Now, my 8800GT can finally rest in peace (although, literally, it's in pieces after the failed 2nd baking). It has served me well...

i bet the 7850 cost less then when u bought ur last card brand new....

we bought an 8800gts 640mb back in '06ish $500AU

replaced it with the current GTX 275 2.5-3 years later $300Au....

2-3 times the power, for less then original price? DONE :D

I had the 8800GTS 640 cards - could over clock them like mad....brought them close to the 8800GT in performance, plus just a touch more VRAM. Then the 8800GTS 512MB cards came out a few months later after I got the 640MB cards. I used EVGA's Step-Up program and got my 640MB cards swapped out for free (minus the cost of shipping).

I found 2 8800GTS 512 in SLI gave about the same performace as a single GTX 280, plus the fact I got the 280s for a lot cheaper then I did the 8800s. As you said, it was a big jump in performance at a cheaper price point.

Going to the 7850 from your old 8800GT - world of difference in GPU power. Hopefully it serves you well.
