Graphics card upgrade (7950) - Will my CPU bottleneck?

post #1 of 15
Thread Starter 
Hello OCN

So I plan on upgrading my graphics card to either an AMD HD 7950 and I have a few questions.
1. Will my CPU bottleneck the 7950?
2. Will my power supply be able to power a 7950?
3. Which 7950 should I get?

Help would be greatly appreciated! biggrin.gif
I want an AMD graphics card because of the free games that come with the card (esp. Far Cry 3).

Get the Sapphire Boost 7950. The card will not bottleneck the 960 (overclock the CPU if need be) and you should be ok with that PSU (on the threshold).

yeah get the Sapphire HD 7950 boost. excellent dual x cooler. 925 mhz boost. Easily overclocks to 1100 Mhz at stock voltage matching HD 7970 ghz performance. and yeah the games are awesome. i finished sleeping dogs and its a very nice game. currently playing Hitman Absolution and like it. farcry 3 seems to be one of the open world shooters in recent times. go for it. thumb.gif

also see if you can overclock your CPU close to 3.8 Ghz. this card needs the CPU power.

if its the rosewill green 530 you will do fine . it has 41A (492w = 41 x 12) on +12v rail. so you should do fine.

Don't listen this Hi-End CPU vs Hi-End GPU "bottleneck" story's.
Most of the times difference only few FPS... and remember your Phenom II so much stronger than PS3 or Xbox processing units
hope you got my point biggrin.gif
My real concern is your 530w PSU, this days 750W is the limit in my opinion,
but from the other side 7950 not that power hungry as 6970's and overall you fine
but still very close to the limits.

Since the rosewill green is not a high quality PSU like the rosewill capstone series, to be on the safer side overclock HD 7950 to 1100 Mhz on stock voltage. try to push Phenom II X4 to 3.8 Ghz.

1. Will my CPU bottleneck the 7950?
Yes, i do have some bottleneck in some games that don't use all my 955 cores but i still get 50+ fps in all games no matter what.
2. Will my power supply be able to power a 7950?
your 530 is more then enough
3. Which 7950 should I get?
Gigabyte or sapphire.
