the amount of texture ram is important, but not nearly as important as the tech specs on the card...

The 9500GT is the lower end of the 9000 series cards from Nvidia, the difference between it and the 8800GT is significant.

Lets take a high end manufacturers card and spec's, assuming the best rather than the worst...
Costs $85.00

Chipset
Chipset Manufacturer NVIDIA
GPU GeForce 9500 GT
Core clock 550MHz
Stream Processors 32
Memory
Memory Clock 800MHz
Memory Size 1GB
Memory Interface 128-bit
Memory Type GDDR2

Now compare that with the 8800GT, a generation older card...
Costs: $130.00
Chipset
Chipset Manufacturer NVIDIA
GPU GeForce 8800 GT
Core clock 600MHz
Stream Processors 112
Memory
Memory Clock 1800MHz
Memory Size 512MB
Memory Interface 256-bit
Memory Type GDDR3

What you see is a significant difference in performance for a very moderate difference in price... Ultimately I don't expect you will have many problems with the 9500gt, but if the system chokes, that video card is going to be a likely candidate.

So for a final contrast, take a look at the GTX280...
Cost: $425.00

Chipset
Chipset Manufacturer NVIDIA
GPU GeForce GTX 280
Core clock 602MHz
Stream Processors 240 processing cores
Memory
Memory Clock 2214MHz
Memory Size 1GB
Memory Interface 512-bit
Memory Type GDDR3

Quadruple the cost, twice the stream processors ( = faster frame rates)

So you can see how a little more money on the bottom end can go a long ways, but a LOT more money on the top end doesn't necessarily push you that much farther... do the 280's rock? I'm told yes... have I dropped $500 on a bleeding edge card? More times than I can count... Will I again? Absolutely.

The one thing I like about bleeding edge video cards is that while you may drop $500 on them, you only do it once every 3-4 years. In the meantime you could be replacing a $150 card yearly... ends up the same in the end...
