Been planning on upgrading for a while now but cash is a bit tight. Just had it forced on me as my old pc packed in. I rely on it for work so I don't have time to spend ages speccing all the best parts and then building it up myself.
I've already ordered a Sapphire Radeon 4870 Card as I read these were very good. Just spotted a Dell Vostro system: Intel Core 2 Quad Q6600, 2 gig RAM, 250 Gig HDD etc. Its a good high tower with plenty of ports etc and its based on the Intel® G33 Express Chipset.
My question is if I grab that then drop a bit more RAM and my Radeon 4870 in - will that be a good gaming machine or are there any obvious bottlenecks (like the motherboard for example)
The g33 motherboard is fine - not fantastic for overclocking, but that rig should be fine for gaming, especially with a 4870 card. You need a new PSU, however. Your generic PSU is not going to be able to handle a 4870.
