Specs: Windows 7, 2.664 GHz / 3327 MB
Hi guys,

I have an old system which runs on an Intel 6750 Core2Duo cpu (not overclocked), 4 GB of DDR2-800 running at 5-5-5 timings and an nVidia 8600GT with 256MB of ram. The Os is Win7 32bit.

The question is: Since my games performance is way lacking in punch, would I benefit from upgrading to, say, an AMD 6770 with 1GB of Ram? I mean, theoretically I would, but will the rest of my system create a bottleneck for this gfx card? Do I definitely need an overall system upgrade? Can I cope for the next 1-2 years or so with keeping this PC but only upgrading the gfx card? Will the difference (if any) be noticeable, so as to justify purchasing this new gfx card?

I need to mention that the target is for me to be able to play games at 1080p.

Thanks in advance :)

It will not be a bottleneck and should help (you have not included all specs).
Look at this chart for comparisons:
Make sure your power supply will handle the card, or you will need to change that out also.

You have to be a little bit crazy to keep you from going insane.

✔ Best Answer
Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.

If you need to get a PS with more capacity, you can usually replace it with any decent quality standard sized standard ATX PS.

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Don't buy an el-cheapo (in quality) PS.
See response 3 in this:

Note - I no longer recommend Cooler Master, Sparkle, or AOpen power supplies.

Geforce 8600GT

Minimum of a 350 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 22 Amp Amps.)

Radeon HD 6770

■450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended
450 x 1.25 = 562.5 watt or greater if you're a gamer.
