Would buying a 7950 cause a bottleneck by the cpu in my system?

post #1 of 11
Thread Starter 
I'm looking to upgrade to a 7950 from a gtx 460 se. I'm just worried my cpu will bottleneck its potential. I'm also worried the psu wont be able to power it properly or if my case will fit it. I'm running the following along with the 460

AMD Phenom II x4 970 3.5ghz
Biostar a780l3g
4gb ddr3 corsair ram
500 watt ocz psu

All in an antec 900 first gen.

No it would not bottleneck a single 7950 much at all but I would overclock that CPU to ensure it doesn't happen. Either way, you will get a significant improvement over your 460.

500 watts is plenty to power that system, the only thing I would look at upgrading would be the RAM. You can get an 8GB kit for $40-$50, some games are starting to use over 4GB with Win 7/8 64 bit.

Would upgrading the motherboard in any way help as well? Because I know the one I currently I have isn't the best.

Yeah, you have a 760G chipset, not really sure about AMD, but I think thats a low end chipset. If you wanna overclock, I reccomend a better motherboard. I'd suggest one, but I know next to nothing about AMD, sorry.

If you upgrade the mobo go for at least a 970 Chipset board, and a 990x or 990fx if you can afford it. There are a few manufacturers that offer some 990fx boards for under $130.

Yeah, that's great mobo for overclocking. I had that mobo and I overclocked my 1090T at 3.8Ghz just by bumping the multiplier. I noticed a big improvement in BF3 when I oc'd my cpu from 3.6ghz to 3.8ghz.

For around that budget (or a little more if you can swing it) I would check out these boards. They are all solid OCers and high quality boards. Plus a few of them support 3-way SLI/CFX if that's your thing.

MSI 990FXA-GD80V2

ASRock 990FX Fatal1ty Professional (I had this board for a while and it was WONDERFUL for OCing. Got my 1055T to 3.75Ghz and my FX4100 to 5Ghz very easily)

Gigabyte GA-990FXA-UD5 (This Gigabyte board has a very high quality power delivery system for some rock solid OCs)

ASUS Sabertooth 990FX

Do not get this msi board (or any msi board on amd), it has a voltage lock of 1.45v and no LLC support.. (so on load you get a voltage lock of like 1.375v or something due to vdroop, which is stupid close to stock) horrible overclocker. Not only that but msi's vrms on amd and customer support are shady.

All the other suggestions on here are great.
