Trying to upgrade old card

They all suck. Whats your budget and current power supply?

gts 250 is better there  what about a hd 7750 or hd 5770 or gts 450 ddr5? can you afford that much? these card will support dx 11 which will be better for gaming 

what your pc spec? budget?

Ok well i only have around 100 to throw around thats why I had put these cards on the list

This is my computer
Motherboard- Biostar N68S3+
CPU- Amd Phenom II X4 840
Hard Drive- Hitachi 160gb
Memory- 4gb DDR3
Video card- Nvidia GeForce 9400 GT 512mb
Power Supply- 600 Watts
OS- Windows 7 (32 bit)

ok so u can buy a hd 7750 best fit for your budget + good performance at that price 

get this one

For $100 you should be able to get a 7750 or a 7770 if you can find one on sale.

Ok well thats why im shying away from that is because I really have 95 this week. I mean you said the 250 is the best one out of all of those? It just seems like my 9400 GT will run games but it really seems to stress and strain.

yup i said that and buy the hd 7750 and be happy dont think of that old cards goodluck 

I dont have enough money for the hd 7750

The 250GTS is much better than the 9400GT - it is placed 14 tiers higher. A good upgrade should be at least 3 tiers higher. The 7750 is only 1 tier above the 250.

14 tiers higher?? I feel like the 9400 GT wasn't built for gaming. It seems to be a normal card.

I know what the tiers mean, its just that's insane

Is the memory on the card even worth looking at?

The 9400GT is not a gaming card. The 250GTS was a good gaming card 2 until about 2 years ago, but if you played games on the 9400 you will have much better performance with the 250. If you are playing at a resolution 1680x1050 or lower the 512MB VRAM will be enough with no AA. If you are playing with higher resolution you will need a card with more memory. None of the cards you listed above is good for gaming except the 250. You will also need to check if your PSU has at least 32A on the 12V rails for the GTS250, If not, will need to save more money and get the 7750 because it consumes much less power.
