Need some rookie advice

[cwarner17]

I was researching all morning, and I ended up buying a HIS Radeon HD 4670 1GB 128-bit graphics card along with a Corsair 400w to power it.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814161287 Graphics Card


After putting in my order, I continued to search and browse information about the graphics card I had purchased, and I came across something that has me very concerned.

http://www.newegg.com/Product/Productcompare.aspx?Submit=ENE&N=100007709%2050002058&IsNodeId=1&bop=And&CompareItemList=48|14-161-287^14-161-287-TS%2C14-161-319^14-161-319-TS

This is comparing the 4670 to the 5760 Redwood. The difference in price is only 8 bucks, but I'm wondering what the catch is?

Newegg says 4670 has:

-25 Mhz Core Clock
-80 Stream Processing Units
+7000 Effective Memory Clock (Typo on the site?)
1GB Memory (4670) vs 512MB (5670)
DDR3 vs GDDR5
+400 RAMDAC
4670 Cooled with IceQ vs 5670 Cooled with Fan


This is my first time purchasing parts to improve performance. With my very vague knowledge, I figured higher graphic card model equals better card. Is this the case?

Did I make a mistake in purchasing the 4670 and should I swap it out for 5670? Like I said the price difference is very minimal and if there is a huge upgrade in performance (mentioned in http://squibtech.com/hardware/videocard/119_amd-ati-radeon-hd-4670-vs-hd-5670.html) I would rather go with the 5670.

Any info is greatly appreciated! Thanks.

The 5670 is a more powerful card they are both benchmarket here http://www.tomshardware.com/reviews/radeon-hd-5570,2552-7.html

In the link you posted are they comparing all 1GB cards?

I suppose I should be asking between

Is the 512MB 5670 better than the 1GB 4670? Is one being cooled with IceQ significanly better than being cooled with a fan?

Yes the HD5670, regardless of memory size, is better than HD4670. Both cards will run into GPU bottleneck sooner than running out of memory with 512Mb installed.
