hi, i am upgrading my computer and i could really use some help. im not exactly a noobie, but im not experienced either. heres the thing,i want to stick with my motherboard, but i want to change my processor and add some ram. i currently have a biostar u8668d v7.1 motherboard. here is the link to the specs (http://www.biostar-usa.com/app/en-us/mb/content.php?S_ID=343). i want a pentium4 processor because it is the best it can handle, and i was thinking on buying an Intel Pentium 4 2.8AGHz 533MHz 1MB Socket 478 CPU, amazon link provided(http://www.amazon.com/dp/B0012MYGNC/?tag=tec06d-20). Is it ok for my motherboard? Now the ram. Theres this guy at my local computer repair who told me my board can handle only 1gb, but at the biostar webpage it says it can handle up to 2gbs, what should i do, stick with 1, or go for 2? and if it supports 2gbs, is this kind of ram ok? (http://www.newegg.com/Product/Product.aspx?Item=N82E16820141217). and... should i get a new fan/psu, or is it ok with what i have already? thanks!
