Hi. I am looking to get a new video card for my Dell 4600. I would mostly use it for lower end computer games such as Civ4 and the Total War series. I am unsure of what to get. I am currently looking at the HIS H130HMH128EN Radeon X1300 HyperMemory 512MB. Is this a good card? I am looking for a card under $100. Also, does anyone know anything about OCZ brand memory? I am looking to upgrade that as well. I have a Dell Dimension 4600 pc with a 3.2Ghz proc. I currently have 512 of ram on it, but am going up to 1.5gb. Thanks.
