Buy a 1gb or a 2gb video card or a DDR3?

I have a 512mb video card and it's kinda slow for some of the games I play.

Is a 1gb enough? or should I spend a little bit more and buy a 2gb video card. Also I need money for a power supply I kinda want to buy the 1gb. also, would a ddr3 make a big difference compared to a ddr2?



Thanks





.|||For the amount of memory here is the chart. If you have a res of 1280x720 or less. 512 is sufficient. If you have up to 1680x1050, a 1gb card is recommended. If you have a 1920x1080 or up, id suggest a 2gb card. Id recommend finding a card with atleast 1gb of vram and GDDR5 memory with at least a 128bit memory bus. Preferably 256bit bus.|||More memory in a card doesn't always mean it's faster, the clock speed, amnount of stream processors is more important.



A 5770 is a very good budget card and you should be able to run most games at reasonable settings.



A decent, branded modular psu should be about £50-70gbp



If you go DDR3 you need a compatible motherboard. It doesn;t make a vast difference anyway unless you have a decent motherboard and cpu and even then if you compare it to decent ddr2 the difference in real world usage is minimal.



Lol please dude trust me, google for yourself ddr2 vs ddr3, these people just read about speeds and think they know all about it.



In actual real terms of real world usage you may gain around 2-5% performance increase.



The biggest bottleneck on most systems is actually the hard drive.



As for gaming it's primarily the graphics card and then the CPU that offer the most noticeable difference to performance.



If you had the same gaming rig and only swapped ddr2 for ddr3 you would be lucky to see an extra 1 or 2 fps difference.|||a 2gig video card is pretty high end, you wouldn't want to get that unless you have other computer parts such as CPU, motherboard, memory that WON'T bottleneck your video card. if you have a super nice video card but your other components of the PC are not up to par, the video card will not perform to its max potential.



ddr3 makes a huge difference compared to ddr2. the price difference between the two might not be THAT dramatic, but the performance gain is huge. go with ddr3.|||okay maybe the other people were thinking memory. But ddr3 makes a reasonable improvement. Also 2 gb is a little over the top. So you better be talking about video cards instead of ram because thats how i answered it|||okay maybe the other people were thinking memory. But ddr3 makes a reasonable improvement.
