Hello, I am looking to upgrade my video card, this is my current system:

http://www.newegg.com/Product/Product.aspx?Item=N82E16883229118

I am limited by budget to around $90 after rebates and obviously an older system. I have been looking at this 6670:

http://www.amazon.com/EAH6670-DIS-1GD5-Radeon-128-bit/dp/B004X8EODY/ref=sr_1_1?s=electronics&ie=UTF8&qid=1365975489&sr=1-1&keywords=asus+6670

or possibly this 7750:

http://www.amazon.com/Sapphire-Radeon-PCI-Express-Graphics-11202-00-20G/dp/B007B5V614/ref=zg_bs_284822_53

However, I am worried that my cpu/ram would cause a bottleneck that would make the 7750 a waste.

Any help would be appreciated, and if there are better 6670/7750 options I'm very open to suggestions, thanks!

Your motherboard uses DDR2, although older I suggest you try a VGA card you selected or even get one within your budget. The reason is that you will perhaps upgrade your motherboard, CPU and RAM
in the near future. Because MB's don't last an eternity. That's why go and buy the VGA you can afford and will work with your PSU. You could buy converters if you lack certain plugs....
As long your PSU can deliver the wattage, it's ok.

Your PSU is 700 watt, if that is a decent one. If it's 80+ % efficiency , you can easily power most VGA cards. a 7770 Radeon can be used with a 500 watt 80+ efficiency PSU.

If CPU/ memory is the bottleneck, No problem....you can upgrade parts..... in the future.
Then you will not regret buying a this more powerful VGA...

before you make a mistake.......... i still use that processor and ddr2-800 in my gaming machine.

what is your monitor/resolution. that alone will dictate a proper card............ and if you don't have at least $170 to spend ( monitor size/res pending ) you;'ll be pissing money away.

The 7770 is a really low budget card that has good performance.... going lower than a 7770 might force you buy a new VGA again in the future. wait and spend $20 more....

I don't think the 7770 will run well in 1920x 1080 if you want to enable all settings with new games....
I have a newer system (low budget), AMD quadcore x4 640, 4GB memory, AM3+ motherboard.
I run the Resident evil 6 benchmark with everything on..... and in the screens where there are many manyzombies my frame rate drops to 7 frame/second. I used the resolution 12xx x 8xx

So, you definitely want to think about a 7770.... 7750 won't cut it!
