[quote name='Warpath01']when buying a new video card, what should you look out for besides the memory (ie 512 mb)? i
Also i have a old sony vaio from 2003, and supposing i buy this card, would there be reasons for it not to work?
- will it fit in my tower ? im currently using an ATI radeon 9200. are they the same size?
-will i somehow have to adjust the amount of electricity my computer uses?
-do i gotta change my main processor to accomodate a different video card?
any help is greatly appreciated.[/quote]
I'm going to hazard to guess that if your system is from '03 that radeon 9200 is either AGP or PCI card type. The 4xxx series radeons (as well as the past couple generations) do not support AGP and only the lower-end models will support PCI. The 4870 itself, is a PCI-express card. This is a newer type of architecture which is much faster than PCI and AGP. You really didn't see PCI-e start showing up on mainstream consumer PC's until around '05-'06. If your CPU is too old to support the video card you want to upgrade to, you might as well buy a new machine (new CPU usually means new motherboard and new memory as well). A lot of times with retail PC's you will need to upgrade the power supply to support a high-end video card. In general, the only way to know what you will be able to support with your system is to look up the specs for your system online by the model number and match that up against the minimum specs required by the card.
