Nvidia 6600gt PCIe

So I just got the 6600gt its 512mb/128bit
it runs most of the stuff i wanta play great but im having problems with Assasins creed and call of duty 5, but call of duty 4 runs great except for a little glitching, I only have 1gig of ram and run vista, think i need more ram or something to do with the GPU

what are the rest of the system specs, such as the cpu and speed/type of memory? If you are unsure, you can load up CPU-Z, and simply run it and it will report all the information we would need.

But on the note of the video card, I do not know how well that graphics card is supported by modern games. Assassins Creed and COD 5 both have the 6600 series listed as a minimum requirement, but if you are having graphical errors you can try updating your drivers, but poor performance will only be solved by upgrading to a faster video card.

The 6600 series is not bad, but its simply old technology and game engines have been developed for newer stuff, so you really wanna use something more modern. For instance, a new HD 4670 will set you back about $70 retail (as low as $50 with mail in rebates), and as you can see here it really out classes the 6600 GT, and in newer games would easily offer twice the performance.

But without some detail on what the "problems" you are having consist of, we really can't help ya out. Adding memory will always improve performance, especially since today the "standard" is 2-4gb, but if you are on older DDR memory you will pay a lot of money to upgrade, if you are on DDR2 memory...well they are practically giving that stuff away...you can find 4gb DDR2 800 kits dropping at $25 with rebates

CPU-AMD Athlon 64 X-2 Dual-Core 2.0ghz
and its DDR2 ram lucky me
I thought I had the latest drivers but I could be mistaken I have the 182.50version
thanx again for the advice Im trying to improve my computer as much as I can to advoid buying a console game system that will be obsolete in a few years without the option to upgrade, but when I upgrade my graphics card I think I want something 256bit I hear 128bit might be holding me back

well the memory subsystem is critical, but loads of memory bandwidth and a huge frame buffer is not going to be put to any use what so ever if the GPU itself is unable to utilize it. And actually, newer cards in the midrange segment are starting to shift away from the 256bit bus, and instead are looking to pair high speed GDDR3 or GDDR5 with a 128 bit bus. The reduced bus complexity means they save money on manufacturing, but dont sacrifice anything when it comes to performance thanks to the high speed memory. The upcoming ATI Radeon HD 4770 is a perfect example of this trade off as it WILL be about 10-15% (if not more in some cases) than the existing HD 4830. As you can see here, despite being limited to a 128-bit memory bus and using some very fast GDDR5 memory, it is able to achieve 51.2gb of memory bandwidth, only 6.4gb less than the HD 4830 which relies on a 256-bit bus. That 6.4gb can be made up easily by bumping that GDDR5 clock speed up another 50mhz, an easy overclock. The 128-bit bus isnt necessarily going to be a limiting factor, it all depends on how its used.

And on the subject of the GPU in particular, you also have to consider the extremely drastic changes that have been made to the design of performance parts since the 6600 GT was released in the middle of 2004. The shift has been away from fixed function pipelines and into independent shader processors, in addition to the new ratio of ROP:TMUs, which has gone from 1:1 or 1:2 into 1:4. All of these changes, paired with game engines optimized for the new architectures, means you can now get huge performance out of very low cost components.

In fact, the HD 2900 XT which was released in 2007 as a $400 video card, is matched or surpassed in performance by the HD 4670 released the end of last year, and is available as $50 graphics card. So simply put, upgrade your video card when you have the money and the market has adjusted to provide the best deals. You are generally much better off upgrading your video card every year or two rather than buying a big expensive card and expecting it to last you for 4 years.

cool thats good to know ill look into that, thanx for clearing that up Im glad technolgies getting cheaper lol I had no idea about the GDDR5 I just back into computers when I left off 512mb was alot of ram haha thanx for the info
