Does Bits changes d performance drastically??

I can't really help you with the Newegg rebate system


But with the new 12.11 drivers the 7770 trades blows with the 6850 but doesn't quite edge it out in benchmarks. The 7770 should work fine on a 450watt power supply, the 6850 is an older card and draws almost twice as much power on idle and load. Higher memory bandwidth can also make a difference ah higher resolutions/ AA settings, so the 6850 might be a bit more capable if you turn those settings up.

Here's a pretty good benchmark test from TechPowerIp with both the 6850 and 7770 using the latest 12.11 drivers for comparison: http://www.techpowerup.com/reviews/AMD/Catalyst_12.11_P...

But keep in mind that the test system in this review is an i7-3770K @ 4.7 GHz with 8gbs of DDR3 @ 1600. So the results won't be quite the same on a lower end PC. Do you know what sort of CPU/ Memory your system currently has? Easiest way to find out is with a program like CPU-Z.

Another option might be to look for a 560ti, 560 or 560se at that price point. But yet again, all three of these cards use a lot more power than the 7770, so you might have to make sure that your system can handle one.

Well, OK. At that price the 7770 is probably your best bet. The only other card that I can find at that price is the 560SE

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

And to be honest the 560SE doesn't have much of a gain at all over the 7770 and uses more power doing it. Also, the ATI card comes with a free copy of Far Cry 3... while the 560 comes with Duke Nukem Forever... and you don't want a copy of Duke Nukem Forever. Trust me. :lol: 

I'm sure the 7770 will give you some adequate gaming performance.

Thanks for the reply...!!
M gettin sapphire card for 104.99$ after rebate
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
And Msi card for aroung 110$
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Which of the above is better????
And u sure about the 450w psu...cuz on AMD site the requirement for 7770 is gives as 500w...
Plz help me out..!!!


The system requirements on Sapphires website suggests that a 450w power supply is good enough:

http://www.sapphiretech.com/presentation/product/?cid=1...

And putting your system specs into this website: http://www.extreme.outervision.com/PSUEngine

LGA775: Core2Duo E7300
4GB DDR2-SDRAM
AMD 7770
DVD-RW drive
7200RPM 3.5" HDD (assuming this is what you have)
Refular Desktop motherboard

It comes out to: 287W at 100% load

But putting your specs into the NewEGG power supply calculator:

http://images10.newegg.com/BizIntell/tool/psucalc/index...

comes to about 300W at max load. I think the NewEgg calculator might be more vague, so they rate power usage higher.

I can't find the requirements for the MSI card, but I would assume that they are similar. Any 450W power supply with a 75% to 80% rating should be able to run this without any issues.

As for which brand.... both have a good reputation. MSI cards generally have better coolers though. But I think either one will be fine.

I think the CORRSAIR VS-450 might be the better buy of the two. Though if you can get a 500w or higher it would even be better. I don't actually know if a 3.0pcie card can work in a 1.1 slot. I know pcie3.0 will work in a 2.0, and I think they are all cross compatible. I am not the person to answer this.
