Hello, i m currently using an integrated Nvidia geforce 7025/nforce 630a GPU. I m planing to buy a HD 6670 DDR3 version GPU. I m wondering how much of a performance increase should i expect.
My other specs are:
Phenom 9500 Quadh @ 2.4 GHZ
2gb ddr2 800MHz ram (planing to add 2 more gigs in a couple of days)
LC POWER SuperSilen 600W PSU
1024x768 17" LCD monitor

Also will my CPU bottleneck the HD 6670 DDR3?
And the last question, at what settings will i be able to play skyrim @ 1024x768 resolution??

Thanks in advance.

Your CPU will not bottleneck the graphics card. You will see very high boost in performance, HD 6670 is around 10-20 times faster than your integrated graphics. You will be able to play at either high or maximum settings - your CPU might hold you back. That's because skyrim is very intensive on the CPU, but it should work fine.

I am not scaring him, in fact, I say it would NOT bottleneck! :)

10-20 times more powerful.....wow that is a lot of performance increase..
I just got skyrim and i m able to play it on 640x480 @ low settings with newest patch ans Skyboost installed. It seems that HD 6670 DDR3 will suit my needs just fine.
Also i may OC the CPU a litle more to like 2.6-2.7GHz when i get some nice aftermatket cooler, now i got some shitty Spire kepler $5 cooler, but it is good enough for current OC. My mobo is MSI k9n6pgm2-v2 AM2+ and it only supports ddr2 ram, so if i get 4gb ddr2 ram @ 800 MHz will it be much slower than 4gigs of ddr3 1333 MHz ram, or does ram speeds have small impact on gaming performance??

RAM speeds have quite small impact on gaming performance. They do have some, but not much. The important thing is to have enough RAM. 4 GB sounds plenty.

What is your budget? You could get a card that has about twice the performance with much less power draw for $110, it also overclocks really well if you'd be interested in that. The card I am mentioning is the 7750, it would also be the best card you could get before your cpu holds back your gpu. Also the best value you can get from a heatsink would be the hyper 212, its about $25. Just make sure it can fit your case.

I have considered 6670 DDR3 ($65), 6670 GDDR5 ($89), and 7750 ($109). Prices I list are average, though the 7750 is consistently standard at $109 and is higher if getting the version without the fan.

Anyway, all three are low power cards and should be fine with my son's existing 300 W power supply. The power data I have seen is that while the 7750 idles with the least power of the three, it generally can use as much power with a load, though the data is inconsistent. Nevertheless, they all seem close in power demand, and all much less power demand than other cards except for maybe weaker cards like the 6450 or 6570?

The 7750 does seem take more room including two slots the best I can tell. In contrast, the 6670 is a single slot card, which I like that. Moreover, as for performance data, the 7750 is not anywhere close to twice as powerful as the 6670 GDDR5 but the 7750 is more powerful and newer technology, and only $20 more.

I would like the 7750. However, I can get the 6670 DDR3 for $40 if the $25 rebate goes through, and the 6670 DDR3 will likely serve its purpose well for the mild gaming my son will do on his computer, especially with his 19" monitor and lower resolution setting. I may get the 7750 for my computer which has a stronger processor and a bigger monitor.

For 32-bit systems, does it do any good to have more than 3.0 or 3.5 GB RAM?

You can only have 4GB Ram max on 32-bit systems. It's good to keep enough ram because some programs use a lot of memory.

Also, I'd get the 6670 GDDR5, it implements a faster performance than a 6670 DDR3.

Thanks for the reply. As for the RAM, I have two slot with 512 MB and two slots with 1GB. I may replace the two 512 MB with two 1 GB to give me a total of 4 GB RAM.

As for the video card, if I were going to get the 6670, I had initially intended to get the GDDR5. Yet, I noticed the 7750 ($109) is only $20 more than the 6670 GDDR5 ($89). I am wondering if my 3+ yr old processor will be bottleneck for the 7750 at higher graphic demands and thus the full extent of the 7750 may not be utilized.

I can get the 6670 DDR3 for $39 if the rebate goes through.

What kind of motherboard do you have? Also, Your RAM must be the same exact specifications such as 1.5 V, same latency and timings, and etc. You might be better off getting a 2 sticks of 2GB of ram. You also have to know what RAM mHz is compatible with your motherboard such as 1066, 1333, etc.

In regards to your graphics card, that may be a possibility. If you don't want to spend much then the 6670 DDR3 may be sufficient for the time being. Since you have older specs.

Good answer. I am likely getting the 7750 because:

(1) it is the apparently the most powerful card I can get with my existing 300 W power supply (let's hope no problem);

(2) also importantly as you indicate it is the best card I can get before my cpu holds me back (for the most part); and

(3) I would rather transfer the newer-technology and more powerful 7750 instead of a 6670 to the new computer in 1-2 years.


With regard to power requirements, the data I have seen is that the 7750 and 6670 are both very low and about the same, with the 7750 having a little lower idle power but at a load possibly exceeding the 6670 a little.

To answer your initial question, my budget is $60-$110 flexible. I am generally willing to spend $ to get best card that satisfies (1) and (2) above. The winner appears to be the 7750 for $100 after rebate, though I may just slap in a 6670 DDR3 for $55 after rebate into this old computer.

Good reply. As for the card, it is a tough decision for me: 6670 DDR3 or 6670 GDDR5 or 7750. I like the 7750 but this is an old computer and I may just get the 6670 DDR3.

As for the memory, I may replace two 512 MB DDR2 with two 1 GB DDR2 and make sure matches existing two 1 GB DDR2 and the motherboard, and thus giving a total 4GB RAM for this Windows Vista 32-bit system.

The motherboard is the Foxconn G33M02 (LGA 775 socket), which I understand is one of the two standard motherboards in the Inspiron 530 (the other being the G33M03), and that my G33M02 does not handle the Quad processors.

Apparently, by the way, the E8500 or E8600 (1333 MHz FSB, 6MB) are the best performing processors for the motherboard, as long as the BIOS has the latest update so that they work. The existing processor is the E5300 2.6 (800 MHz, 2MB). Performance of the E8500 appears about 20-30% over the E5300.
